Description

The inhibiting device that reverses gear of four-wheel motor cycle

Technical field

The utility model relates to a kind of shift device, is specifically related to a kind of inhibiting device that reverses gear of four-wheel motor cycle.

Background technology

The inhibiting device that do not reverse gear on the common common four-wheel motor cycle gearshift can directly be converted to from forward gear in the high-speed cruising process and reverse gear.Be in the high-speed cruising state owing to be positioned at the driving engine of forward gear, in-engine gear is the forward high speed revolution, if directly be changed to four-wheel motor cycle by neutral and reverse gear this moment, need apply opposition to high-revolving gear, make the gear of forward high speed revolution carry out contrarotation, the gear of forward high speed revolution is subjected to opposition suddenly, produces huge inertia the gear of high-speed cruising is destroyed tooth and damaged driving engine and four-wheel motor cycle, influences driver and crew's safety.

Summary of the invention

The purpose of this utility model is, a kind of inhibiting device that reverses gear of four-wheel motor cycle is provided, and adopts this device four-wheel motor cycle when reversing gear, need earlier motor bike to be braked, the operation of reversing gear again under the slow speed of revolution of driving engine can not damage the gear of driving engine, driving engine long service life.

The purpose of this utility model is achieved in that the variable block device is connected on the base, the variable block master arm of variable block device is connected with variable block device slave arm by pull bar, a telescopic restraint device that reverses gear is set on the base, the restraint device that reverses gear is connected with brake pedal by flexible flexible axle, on the restraint device firm banking, and be positioned at a side of variable block master arm.

Adopted such scheme, a telescopic restraint device that reverses gear is set on base, the restraint device that reverses gear is positioned at a side of variable block master arm, the end protuberate basic unit of position-limited lever of inhibiting device reverses gear, can limit the variable block master arm by advance gear or the neutral position Direct Transform position of reversing gear, driving engine enters under high rotating speed and reverses gear when preventing to reverse gear.In the time of need reversing gear, step on brake pedal and power can be passed to the inhibiting device that reverses gear by flexible flexible axle, the position-limited lever of the inhibiting device that reverses gear is overcome in the locating bush of elastic force indentation inhibiting device of pull back spring, for the variable block master arm is stepped down, the variable block master arm turns to the position of reversing gear by forward gear position or neutral gear position, owing to also motor bike is braked when trampling brake pedal, the aperture of throttle reduces, the rotating speed of driving engine is reduced, under the slow speed of revolution of driving engine, reverse gear, the infringement of being damaged property of engine gear can be avoided like this, in the service life of guaranteeing engine gear, the safety of driving driver and crew can be increased simultaneously.

Description of drawings

Fig. 1 is an assembly structure figure of the present utility model;

Fig. 2 be along the A-A among Fig. 1 to the local section constructional drawing;

In the accompanying drawing, 1 is brake pedal, and 2 are extension spring, and 3 is mount pad, and 4 is flexible flexible axle, and 4a is a steel rope, 5 is base, and 6 is the variable block handle, and 7 is the variable block master arm, and 8 is the variable block device, and 9 is position-limited lever, 10 is pull back spring, and 11 is locating bush, and 12 is hollow pipe link, and 13 is nut, 14 flexible axle adapter sleeves.

The specific embodiment

Referring to Fig. 1 and Fig. 2, brake pedal 1 is articulated on the mount pad 3 by locating dowel pin, and brake pedal 1 forms with mount pad 3 and flexibly connects.Variable block device 8 is assemblied on the base 5, brake pedal 1 is connected with an end of a flexible flexible axle 4, brake pedal 1 connects flexible flexible axle 4 by extension spring 2, flexible flexible axle 4 is a drag-line, flexible flexible axle 4 is provided with Adjusting bolt Adjusting screw and the adjusting screw(rod) of adjusting this flexible flexible axle sum of errors elasticity, and Adjusting bolt Adjusting screw and adjusting screw(rod) are respectively by the jam nut locking positioning.The other end of flexible flexible axle 4 connects the telescopic restraint device that reverses gear, and this inhibiting device that reverses gear is arranged on the base 5, and is positioned at a side of variable block master arm 7.The restraint device that reverses gear is connected with brake pedal by flexible flexible axle, and the restraint device that reverses gear comprises the locating bush 11 that is fixed on the base, hollow pipe link 12, an end and flexible flexible axle bonded assembly position-limited lever 9 and pull back spring 10.Locating bush 11 is captiveed joint with base 5 by a nut 13, the outside wall surface of this nut is provided with the outside thread with base 8 screws thread fit, screw thread on the nut 13 centre hole walls is used for and locating bush 11 screws thread fit, and nut 13 is captiveed joint with base 5 with locating bush 11 respectively by screw thread fit.Nut 13 is a ladder nut, the outside thread that the path section setting of this ladder nut is threaded with base 5.Hollow pipe link 12 1 ends are fixedly connected in the locating bush by screw thread fit, and the other end is threaded with flexible flexible axle adapter sleeve 14.The end that position-limited lever 9 connects flexible flexible axle is arranged in locating bush, the steel rope 4a of flexible flexible axle passes hollow pipe link 12 and is connected with position-limited lever, the other end of position-limited lever and locating bush form free-running fit and stretch out locating bush outward, and the two ends of pull back spring 10 are against respectively on the limited step of the bottom of hollow pipe link and locating bush.The end that position-limited lever 9 connects flexible flexible axle is provided with limited step, and pull back spring 10 is enclosed within on the position-limited lever spacing by limited step.

When needs reverse gear to four-wheel motor cycle, trample brake pedal 1 power is passed to inhibiting device by flexible flexible axle 4, the position-limited lever 9 of the inhibiting device that reverses gear is overcome in the elastic force indentation locating bush of pull back spring 10, for the variable block master arm 7 of variable block device 8 is stepped down, handle the variable block handle 6 of variable block device 8, make variable block master arm 7 turn to the position of reversing gear by forward gear position or neutral gear position.Because also motor bike is braked when trampling brake pedal 1, at this moment the aperture of throttle reduces, make the rotating speed of driving engine reduce, under engine low rotation speed state, reverse gear.Reverse gear behind the EO, unclamp the pressure of pin to brake pedal 1, position-limited lever 9 is got back to initial position automatically under the tension force effect of pull back spring.

Though the utility model discloses as above with preferred embodiment; right its is not in order to limit the utility model; any person of ordinary skill in the field; in the spirit and scope that do not break away from the utility model; when can doing a little change and improvement, so the protection domain of the utility model is as the criterion when looking the claim person of defining.
