Abstract
Disclosed is a combined braking handspike, pertaining to vehicle transmission technical field, comprising a handspike, a handspike spring, a handspike sleeve, a handspike head, a brake ratchet, a brake ratchet pin, an offset spring for the brake ratchet and a link stopper; wherein one end of the handspike is connected with a rocker and the other end of the handspike is sheathed into the handspike sleeve; the handspike spring is hitched on the handspike; the handspike head is installed below the brake ratchet and above the link stopper; the brake ratchet is meshed with the brake gear of a driven belt wheel so as to brake and stop the vehicle. The combined braking handspike is simple in structure, low in cost, small in bearing force, good in brake effect and stable and reliable in performance.
Description
Technical field
The utility model relates to a kind of locking device for a vehicle of metal band type stepless speed variator, belongs to the system of vehicle transmission technical field.
Background technique
The function of vehicle drive system is exactly that power with power source is passed to driving wheel, and changes the tractive force and the speed of a motor vehicle according to the requirement of vehicle driving.The stepless change transmission is the development trend of system of vehicle transmission, be considered to the optimal kind of drive, stepless transmission agent can be according to the change speed ratio of vehicle road travel situations and engine behavior continuous stepless the ratio of output speed (input speed with), thereby make motor always work in zone the most efficiently, realize the optimum Match of ambient conditions and vehicle, make vehicle obtain best rideability.
Be provided with following several gears: P (Parking) in the stepless speed variator system, R (to shelves), D (driving shelves), L (bottom gear), N (neutral gear).The driver can handle gearshift mechanism according to different needs.When the driver selects the Parking gear, a kind of actuator of parking braking just must be arranged.
Summary of the invention
Technical problem to be solved in the utility model is: actuator---the brake pushrod component that a kind of parking braking is provided when selecting the parking braking gear for the vehicle stepless speed variator system, simple in structure, stressed little, with low cost, part processing is less demanding, and working stability is reliable during parking braking.
The technical solution adopted in the utility model is: this brake pushrod component is by push rod, push rod spring, pushing rod sleeve, push rod cup, stop pawl, the braking pawl pin, the stop pawl reduction torsion spring, link stopper is formed, push rod one end is inserted in the pushing rod sleeve, and suit push rod spring on push rod, the push rod the other end connects rocking arm, push rod cup places under the stop pawl termination, on the block, the moving pawl pin of stop pawl coiling can rotate, the braking pawl pin is fixed on the housing, and on the braking pawl pin suit stop pawl reduction torsion spring, the braking gear teeth in stop pawl head and the vehicle stepless speed variator system on the passive belt wheel match.
The utility model is its effect that realizes like this: the parking braking rocking arm is converted to moving of brake pushrod with the rotation of gear controlling rod.
The brake pushrod head promotes the moving pawl pin of stop pawl coiling and rotates, and the stop pawl head is to the parking braking gear teeth motion of passive belt wheel.If the gear teeth just in time are in and the stop pawl head can intermeshing position, push rod can whole move along link stopper so, stop pawl is rotate in place and brakes the gear teeth in conjunction with firm.Can not be intermeshing during the position if the stop pawl and the braking gear teeth are in, stop pawl can't move and put in place and gear teeth meshing so.The axle sleeve conical surface on the brake pushrod will be braked pawl and withstood this moment, can't advance and put in place.At this moment, push rod spring will be compressed.When vehicle occur to slip the trend of car, the gear teeth on the passive belt wheel can turn to can with the intermeshing position of stop pawl head, at this moment, under the effect of push rod spring power, putter sleeve will move and put in place, utilizes the plane on the axle sleeve that stop pawl is withstood, and makes it can effectively stop the slide car.
When stop pawl is in braking state, be subjected to the effect of stop pawl reduction torsion spring.Withdraw from application position at push rod, when stop pawl no longer is subjected to the torque of pushing rod sleeve, can under very little spring force effect, return to original non-braking working state.
In addition, in order to guarantee that stop pawl can mesh or throw off smoothly.The shape of stop pawl head and passive belt wheel Brake drum tooth is standard tooth form.
The utlity model has simple in structure, during parking braking motion reliable, and stressed little, the processing request of part is not very strict characteristics, with low cost, certain application prospect is all arranged on all vehicles.
Description of drawings:

Embodiment:
Referring to Fig. 1, the utility model is by push rod 1, push rod spring 2, pushing rod sleeve 3, push rod cup 4, stop pawl 5, stop pawl reduction torsion spring 6, braking pawl pin 7, link stopper 8 is formed, push rod 1 one ends are inserted in the pushing rod sleeve 3, and suit push rod spring 2 on push rod 1, push rod 1 the other end connects rocking arm 9; rocking arm 9 and gear controlling rod link together by straight pin; push rod cup 4 is installed under the stop pawl 5; on the link stopper; stop pawl 5 can rotate by the moving pawl pin 7 of coilings; the braking pawl pin is fixed on the housing; also be set with stop pawl reduction torsion spring 6 on the braking pawl pin 7, and the braking gear teeth in the stop pawl head of stop pawl 5 the other ends and the vehicle stepless speed variator system on the passive belt wheel match.
The utility model is converted to moving of brake pushrod by the parking braking rocking arm with the rotation of gear controlling rod.
When parking braking, at first the brake pushrod head promotes the moving pawl pin rotation of stop pawl coiling, and the stop pawl head is to the parking braking gear teeth motion of passive belt wheel simultaneously.If the gear teeth just in time are in and the stop pawl head can intermeshing position, push rod can whole move along link stopper so, stop pawl is rotate in place and brakes the gear teeth in conjunction with firm.Can not be intermeshing during the position if the stop pawl and the braking gear teeth are in, stop pawl can't move and put in place and gear teeth meshing so.The axle sleeve conical surface on the brake pushrod will be braked pawl and withstood this moment, can't advance and put in place.At this moment, push rod spring will be compressed.When vehicle occur to slip the trend of car, the gear teeth on the passive belt wheel can turn to can with the intermeshing position of stop pawl head, at this moment, under the effect of push rod spring power, putter sleeve will move and put in place, utilizes the plane on the axle sleeve that stop pawl is withstood, and makes it can effectively stop the slide car.
When stop pawl is in braking state, be subjected to the effect of stop pawl reduction torsion spring.Withdraw from application position at push rod, when stop pawl no longer is subjected to the torque of pushing rod sleeve, can under the effect of very little spring force, return to original off working state.
The shape of stop pawl head and passive belt wheel Brake drum tooth is standard tooth form, can guarantee that like this stop pawl can mesh or throw off smoothly.
