Abstract
The utility model relates to a combined governing differential, which comprise a set of governing gears, a set of differential components and a cabinet as well as a bog and a small sprocket wheels and a tooth-shaped chain, wherein the governing gear is positioned at the front part of the cabinet. The output shaft at the end of the wheel is provided with a small sprocket wheel; the differential components are installed at the rear of the cabinet. The shell of the component is provided with a big sprocket wheel; the two sprocket wheels are connected through the tooth shape chain, thereby forming a combined device integrating the governing, decelerating and differential functions. The utility model integrates three devices in the driving system in the vehicle. Not only the transmission is stable with small volume, but also the structure is simple and the service life is long, so the device is especially fit for use on the mini-car and the tricycle.
Description
One, technical field:
The utility model relates to Transaxle, specifically relates to a kind of knockdown vehicle speed variation differential mechanism.
Two, background technique:
In the traveling mechanism of vehicle, speed changer and differential mechanism all are the important device of transferring power.The effect of speed changer is to change speed ratio and torque ratio, and it cooperates with motor, guarantees that vehicle has good power character and Economy.Differential mechanism and effect are to regulate rotating speed, guarantee that at Ackermann steer angle two sidecar wheels rotate with different rotating speeds, to adapt to the needs that vehicle travels under multiple road conditions.
Generally, speed changer and differential mechanism be independent device be again the association of transferring power.Because still rotating speed is higher for the power of speed changer output, also be provided with the one-level speed reducer at the front end of differential mechanism, just formed the complete system of vehicle transmission mechanism of a cover through speed change, deceleration, differential like this, this also is the kind of drive that the current mobility vehicle generally adopts.
Along with automobile day by day to the emerge in multitude of miniaturization development and regular three-wheeled motor, discrete speed change, deceleration, differential mechanism have shown it and have taken up room greatly, and power loss is big, use weakness such as part is many, so can't adapt to the demand of above-mentioned vehicle, be inexorable trend therefore to the integration development.
Three summary of the invention:
The purpose of this utility model provides a kind of combined type speed change differential mechanism, and he combines functions such as speed change, deceleration, differential together, is particularly suitable for using on compact car.
The technical solution of the utility model is as follows:
A kind of combined type speed change differential mechanism comprises one group of speed change gear, a cover differential member and a casing, and he also comprises small one and large one two sprocket wheels and a silent chain; Described speed change gear is installed in the front portion in the casing, a minor sprocket is housed on the output shaft of train end, described differential member is installed in the rear portion in the casing, a big sprocket wheel is housed on the member shell, described two sprocket wheels are connected by silent chain, and having constituted speed change, deceleration, differential thus is the composite set of one.
Combined type speed change differential mechanism described in the utility model is compared with discrete speed change, differential mechanism, has following advantage:
1, this apparatus structure compactness, a thing multipotency is applied on the vehicle and can reduces weight and space, for manufacturing and designing of compact car provides convenience.
2, retarder is stressed very big parts in the power train, adopts gear reduction easily to make tooth surface abrasion because of Surface of action is less, influences working life.This device is born transmission, deceleration task with silent chain, has not only utilized the characteristics that chain sheet and tooth bearing are big, the stable drive noise is little, and has prolonged parts working life greatly.
3, this device is contained in speed change differential parts collection in the housing, has reduced component and transmission link, so low cost of manufacture, the transmission efficiency height.
Four, description of drawings:
Fig. 1 is a kind of structural representation of combined type speed change differential mechanism.
Five, embodiment:
Referring to Fig. 1, a kind of combined type speed change differential mechanism comprises speed change gear 1, differential member 2 and casing 3.It also comprises hinge wheel 4 minor sprockets 5 and silent chain 6.
Described speed change gear 1 is installed in the front portion of casing 3 inner chambers, and minor sprocket 5 is housed on its output shaft; Described differential member 2 is installed in the rear portion of casing 3 inner chambers, and hinge wheel 4 is housed on the shell of member 2; Described sprocket wheel 4 is connected by silent chain 6 with sprocket wheel 5, and having constituted speed change, deceleration, differential thus is the composite set of one.
The utility model integrates three kinds of devices in the vehicle driving system, and not only the stable drive volume is little, and the life-span simple in structure is long, is particularly suitable for using on minicar and regular three-wheeled motor.
Claims (2)
