Abstract
The utility model relates to an one-way brake device for vehicle, which prevents vehicle coasting grade after the motor vehicle or electric vehicle loses power during running on the ascent. The one-way brake device has a structure that a star-shaped ring in which a convex ring is provided in the intermediate of inner wall of the star-shaped ring and ratchets are provided on the inner wall of the convex ring; a baseboard is provided in the star-shaped ring, wherein the baseboard has an axle hole, three-layer steps are indent in the cylinder surface, grooves are symmetrically arranged on the axial surface of the second layer step, and a drill hole is provided at the bottom in the groove; a spring wire or a spring tab is inserted in the drill hole, a brake block matched with the ratchet is provided in the groove above the spring wire or the spring tab spring, a pressure cover having an inner bore and whose cylinder surface is indent with a step is provided above the baseboard, and balls are provided at both sides of the star-shaped ring convex ring between the pressure cover and the star-shaped ring as well as the baseboard cylinder surface. the device does not affect built-in braking system of the vehicle, when the brake rubber holds the star-shaped ring, the baseboard can only spin counterclockwise, the vehicle can only advance rather than fall back, so that the skate cycle and vehicle starting operating danger can be avoid during parking on the ascent.
Description
Technical field the utility model relates to when being used for running out of steam when battery-driven car, self-propelled vehicle travel on uphill road, and braking prevents to slip a kind of automobile-used one-way braking means of car, is particularly suitable for being installed on the battery-driven car and uses.
Background technology automobile-used brake system of the prior art all is a bi-directional braking, and is inactive before and after the vehicle body of braking back; The interlock outage does not have the power supply of driving behind the electric vehicle brake; When restarting after battery-driven car or self-propelled vehicle stop on uphill road like this, easily produce the sloping phenomenon of slide, and be directed at unexpected the generation.
Summary of the invention opens the deficiency that exists in the car operation in order to overcome in the prior art outage of automobile-used brake system bi-directional braking and electric vehicle brake after uphill road stops, avoid slipping the generation of sloping phenomenon and the contingency that causes, the utility model provides a kind of automobile-used one-way braking means.The design plan of the automobile-used one-way braking means of the utility model is: include the rim brake handle identical with bicycle hand brake that is fixed on the handlebar in its structure, with rim brake the bonded assembly brake cable, be enclosed within the outer brake cable pipe box of brake cable, on the brake cable pipe box, be provided with and connect to ground, the adjustment nut of the fixed mount of stepping brake spool cover and adjustment fixing spring, the other end of brake cable is connecting the brake rubber block of annular opening, brake rubber block one end is fixed on bolt of rear end plate on the vehicle frame, have bulge loop in the middle of also including the inwall that is located in the brake rubber block, the sour jujube circle that has ratchet on the bulge loop inwall, in the sour jujube circle, be provided with one and have axis hole, contract in the periphery three layers of step are arranged, symmetry is provided with groove on the axial surface of second layer step,, there is the base plate of a boring at the end in the groove, in the boring of base plate, be inserted with spring wire or spring leaf, be provided with one in the groove above spring wire or spring leaf and have the slipper that cooperates the inclined-plane with ratchet, above base plate, be provided with base plate is fastening and have an endoporus, contracting in the periphery has the gland of a step, and is located at sour jujube circle bulge loop both sides, ball between sour jujube circle and base plate and gland.Automobile-used one-way braking means of the present utility model is simple in structure, easy to operate, base plate is fixed on the electric vehicle hub axle sleeve, do not influence the original brake system of battery-driven car, so do not cut off the power supply during this device brake, when holding rim brake after mentioning brake cable, it is motionless that brake cable drive brake rubber block grips the sour jujube circle that firmly has ratchet, base plate in the sour jujube circle is done the conter clockwise unidirectional rotation along the sour jujube circle, battery-driven car can only advance, can not retreat, so just realize the one-way brake of car, car takes place when opening car to slip can to prevent that vehicle from travelling to stop on uphill road, avoid opening the danger of car operation, strengthened the security and stability of car.
Description of drawings Fig. 1, be the structural representation of the automobile-used one-way braking means of the utility model.Fig. 2, be the generalized section of A-A among Fig. 1.
The specific embodiment has further understanding for structure and the principle to the automobile-used one-way braking means of the utility model, and details are as follows in conjunction with the accompanying drawings:
With reference to Fig. 1, Fig. 2, comprised in the automobile-used one-way braking means structure of the utility model that the rim brake identical with bicycle hand brake that is fixed on the handlebar is 1, with rim brake 1 bonded assembly brake cable 2, be enclosed within the brake cable pipe box 3 outside the brake cable 2, on brake cable pipe box 3, be provided with and connect to ground, brake cable pipe box 3 is fixed on the fixed mount 4 on the vehicle frame and adjusts the adjustment nut 6 of fixing spring 5, the other end of brake cable 2 is connecting the brake rubber block 7 of annular opening, the other end of brake rubber block 7 is fixed on the vehicle frame by bolt of rear end plate 8, have bulge loop in the middle of in brake rubber block 7, being provided with an inwall, the sour jujube circle 9 that has ratchet on the bulge loop inwall, in sour jujube circle 9, be provided with one and have axis hole, contract in the periphery three layers of step are arranged, symmetry is provided with groove on the axial surface of second layer step,, there is the base plate 10 of a boring at the end in the groove, in the boring of base plate 10, be inserted with spring wire or spring leaf 11, be provided with one in the groove above spring wire or spring leaf 11 and have the slipper 12 that cooperates the inclined-plane with ratchet, above base plate 10, be provided with base plate 10 is fastening and have an endoporus, contracting in the periphery has the gland of a step 13, and encloses 9 bulge loop both sides sour jujube, the ball 14 that between sour jujube circle 9 and base plate 10 and gland 13, is provided with.When brake rubber block 7 grip sour jujube when enclosing 9 sour jujube enclose 9 motionless, put fixing base plate 10 at hub spindle and can only do the anti-clockwise rotation, if base plate 10 clockwise rotates, slipper 12 has withstood the ratchet of sour jujube circle under the effect of spring wire or spring leaf 11, so wheel can only advance, can not retreat, realize one-way brake.
When this automobile-used one-way braking means is installed on the self-propelled vehicle, the 1-8 parts among the figure can be used instead hydraulic pressure or the air pressure part of using in the brake system on the self-propelled vehicle.
