Description
Technical field
The utility model relates to a kind of mid-get car retarder, relates in particular to front reduction gear of mini-size car suspension connecting device.
Background technology
At present, the front-wheel of mid-get car generally connects to ground by suspension fork mechanism, and front-wheel is a flower wheel, does not have propulsive effort.When the power of driving engine was delivered to back axle by rear propeller shaft and drives the trailing wheel rotation, front-wheel rotated in the same way with trailing wheel, and car load travels forward or backward.Have only two trailing wheels that the mid-get car of propulsive effort is arranged,, by the lower road surface of adhesive ability coefficient the time, can not provide enough big surface driving power though can reduce the wearing and tearing of tire and Parts for Power Train preferably during travels down at condition of road surface; During particularly by muddy or frost boiling highway section, drive wheel is absorbed in mire easily or can't drives because of skidding, thereby has influenced the crossing ability of mid-get car, brings great inconvenience for people's trip.
The dynamic property and the crossing ability that how to improve mid-get car are the difficult problems that all mid-get car manufacturers are just studying intensively, the producer's imagination that has is that mechanism substitutes with the front wheel suspension mechanism of traditional mid-get car with bridge, the power of driving engine can be transferred by auxiliary gear box, and pass to front reduction gear and propons semiaxis by front propeller shaft, so that mid-get car is selected four wheel drive as required for use.The structure of front reduction gear can design with reference to the back retarder, but the mounting means of front reduction gear but can not be indiscriminately imitated the pattern of back retarder, and because of back axle need carry and outputting power, so back retarder and back axle are integral, back axle connects to ground by leaf spring; And front reduction gear is an outputting power, is subjected to the restriction of function and installation site, and is how easy on vehicle frame, securely front reduction gear to be installed be mid-get car manufacturer problem extremely to be solved.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of front reduction gear of mini-size car suspension connecting device, so that front reduction gear is installed on vehicle frame, makes mid-get car select four wheel drive as required.
The technical solution of the utility model is as follows: a kind of front reduction gear of mini-size car suspension connecting device, comprise front reduction gear, its key is: left and right overarm is arranged in parallel above described front reduction gear, on hanging oneself from a beam before the front end of two overarms all is fixed on, be symmetrical arranged two hangers in the bottom surface of preceding overarm, two hangers are positioned at the and arranged on left and right sides of the anterior journal stirrup of front reduction gear, and are connected with journal stirrup by bolt; In the both sides at described front reduction gear rear portion a support is installed respectively, the middle part anchor post of each support lateral surface, the bearing that suspends after being set with on this pillar, the bearing that suspends after described is connected with the back suspension block by bolt, and back suspension block symmetry is fixed on the bottom surface of described left and right overarm postmedian.
In the utility model, the two of preceding overarm and the tail end of left and right overarm form an integral body by the vehicle frame of welding and mid-get car, the journal stirrup of front reduction gear front portion is connected with hanger in the preceding overarm by bolt, the support that install both sides, front reduction gear rear portion by after suspend back suspension block bolted connection in bearing and the overarm, front reduction gear adopts the above mechanism of hanging oneself from a beam to connect to ground, structure is simple relatively, not only connects firm, easy accessibility, and overall weight is light, cost is lower.
The utility model can make front reduction gear easy, be installed on the vehicle frame securely, the front wheel suspension mechanism of so traditional mid-get car is that mechanism substitutes by bridge, this bridge is that two front-wheel semiaxis are connected with two mouths of front reduction gear in the mechanism, the input end of front reduction gear is connected with auxiliary gear box by front propeller shaft, can the transfer power of driving engine of auxiliary gear box, and pass to front reduction gear and propons semiaxis by front propeller shaft, so that mid-get car is selected four wheel drive as required for use, tractive force is enough big like this, strengthen the hill climbing ability of mid-get car greatly, effectively improved the crossing ability of automobile.Preferably during travels down, auxiliary gear box is not given front reduction gear with the transmission of power of driving engine to mid-get car at condition of road surface, and mid-get car adopts two back-wheel drives, can reduce the wearing and tearing of tire and Parts for Power Train.Mid-get car can adopt two-wheel drive, can adopt four wheel drive again, for people's trip brings great convenience.
In the via hole of above-mentioned front reduction gear journal stirrup, be provided with shock-absorbing sleeve, this shock-absorbing sleeve is made of inner metal sleeve, metal-coating and rubber bodies, wherein rubber bodies is between inner metal sleeve and metal-coating, and the three is by being tightly fixed together, and metal-coating and front reduction gear journal stirrup flush fit.Between shock-absorbing sleeve and the front reduction gear journal stirrup, and constitute between inner metal sleeve, metal-coating and the rubber bodies of shock-absorbing sleeve and all adopt flush fit, be connected firmly like this and reliable, can effectively prevent to come off; Shock-absorbing sleeve can play the effect of damping, passes to the vibratory magnitude of vehicle frame to reduce front reduction gear by journal stirrup, improves the traveling comfort of driving.
Outside face in above-mentioned rubber bodies has breach, and the shape of breach can be varied, and the existence of breach makes rubber bodies elastic stiffness coefficient reduce, and can play better cushioning effect.
Above-mentioned support is a platy structure, and the two ends of frame bottom respectively are connected with front reduction gear by a bolt, and the top of two stands bends relatively towards central authorities, and bending part is connected with front reduction gear by bolt.Support is connected with front reduction gear by 3, and both connect reliably, and easy accessibility.
Suspend after the above-mentioned rear portion of bearing is connected with the back suspension block by bolt, after the suspend front portion of bearing be tubular structure, in pipe, be provided with internal lining pipe and rubber ring from inside to outside successively, internal lining pipe and rubber ring and after the bearing flush fit that suspends.Rubber ring can play the effect of damping, with reduce front reduction gear by after the bearing that suspends pass to the vibratory magnitude of vehicle frame, and improve the traveling comfort of driving; Internal lining pipe, rubber ring and after the bearing flush fit that suspends, the three is connected firmly, and can effectively prevent to come off.
The outline molded lines of above-mentioned internal lining pipe is a cam, relatively rotates between rubber ring and the internal lining pipe avoiding.
Outside face at above-mentioned rubber ring has breach, and the shape of breach can be varied, and the existence of breach makes rubber ring elastic stiffness coefficient reduce, and cushioning effect is better.
Beneficial effect: the utility model has solved the installation difficult problem of front reduction gear of mini-size car, makes mid-get car select for use two-wheel drive or four wheel drive to become a reality as required.Front reduction gear adopts overarm mechanism to connect to ground, and structure is simple relatively, not only connect firm, easy accessibility, good damping effect, and overall weight is light, cost is lower.
