Abstract
The utility model relates to a mechanical synchronous braking device for motor vehicles, which is particularly suitable for the mechanical synchronous braking devices on small-four-wheel tractors or other miniature main motor vehicles and trailers. The main motor vehicles and trailers of the existing small-four-wheel tractors have the problems of high cost and no synchronous braking. The utility model aims to provide a mechanical synchronous braking device for motor vehicles, which has the advantages of sensitive braking when braking, simple manipulation, simple structure, low cost, and convenient adjustment and maintenance. The utility model is characterized in that the forward movement of the brake pull rod of a host machine drives the forward swing of a brake rocker arm, and the host machine is caused to be braked; the forward movement of the brake pull rod of a trailer is driven by flexible linkage devices such as a brake pull wire, a spiral steel pipe, etc.; the trailer is also caused to be braked, and the goal of synchronous braking is achieved.
Description
The utility model relates to a kind of self-propelled vehicle mechanical type synchronous braking device, particularly is applicable to the mechanical type synchronous braking device on small four-wheel tractor and other equipment of small motor car owner, the trailer.
The pony truck trailer of railroad platform use does not at present have brake equipment, and what small four-wheel tractor master, trailer used is the collision type brake equipment.This device is for asynchronous braking, after its principle is the trac. braking, is lower than the velocity contrast of trailer moving velocity by its moving velocity, allows the trailer collision promote rocking arm from one's body brake push rod, finishes the braking of trailer.But this kind braking has such problem, at glancing impact, because trailer produces thrust to main frame, makes main frame to preacceleration again, causes trailer braking protection valve to be automatically terminated.Therefore, whole braking procedure trailer occurs and main frame intermittently collides, the phenomenon of cadence braking, and the unit braking procedure is prolonged.And this braking is gone up a slope and can not be braked, and causes the slide slope easily; Interrupted collision of descending and braking, it is very not steady to drive a vehicle.Easily knock main frame when sharply turning or emergency braking over.
For addressing this problem, produce tractors producer or user of ground such as Luoyang changes the collision type braking of former trailer into oil (gas) formula or hand lever mechanical braking.Though the hand lever mechanical braking has solved to go up a slope and can not brake and the descending turning car group not plateau problem that travels, be unrealized main, trailer synchronous braking, especially when emergency braking, the chaufeur brake must hand, pin and usefulness, is difficult to implement in time this operation.
And oil (gas) though compacting moving handle light, braking is reliable, has realized synchronous braking, its complex structure, involve great expense, often et out of order, dismounting maintenance are loaded down with trivial details, it is standby that vapour-pressure type also need be installed a cover mechanical type braking in addition.It is difficult to promote the use of on small four-wheel tractor and trailer.
The purpose of this utility model be a kind of braking sensitivity that can use on cyclecar and trailer will be provided, manipulation is convenient, simple in structure, cost is low, adjust mechanical type synchronous braking device easy to maintenance.It can guarantee at main frame glancing impact trailer also together braking.
The purpose of this utility model is achieved in that before the existing hand lever braking of trailer and adds peace one mechanical type master, trailer synchronous braking device.When chaufeur depressed foot brake pedal, main frame lever connection (6) drove brake rocker arm (5) forward swing, the main frame braking; Rocking arm (5) drives brake pulling wire (4) reach again simultaneously, brake pulling wire (4) passes in the helical steel pipe (1) of bending arbitrarily, and helical steel pipe (1) two ends are dragged permanent seat (3), (8) on the thick stick (9) fixing by main frame axle shaft housing (7) and trailer respectively.Because of brake pulling wire (4) links to each other with parking brake lever (11) by adjusting hook (10), parking brake lever (11) drives trailer braking protection valve pull bar (12) reach also along with forward swing, and trailer is also braked, and main, trailer reaches synchronous braking.
The utility model is because only need to fix a helical steel pipe and connect a brake pulling wire at trailer parking brake lever front end, so cost of installation is low; Moreover, because of on hand lever, teasing and ridicule whole hole, be equipped with and adjust hook, so dismounting is easy to adjust; In addition because it has realized master, trailer synchronous braking, so handle convenient, braking sensitivity.
The concrete structure of utility model is provided by following embodiment and accompanying drawing thereof.
Fig. 1 a.b is according to the mechanical type synchronous braking apparatus structure scheme drawing that the utility model proposes.
Describe details and service condition in detail below in conjunction with Fig. 1 according to the concrete device that the utility model proposes.
This device comprises a helical steel pipe (1) of bending arbitrarily, its two ends are fixed on main frame axle shaft housing (7) and trailer respectively and drag permanent seat (3), (8) lining on the thick stick (9), be with oil resisting rubber hose (2) outside it, a brake pulling wire (4) is passed in inside.Backguy (4) one ends link to each other with main frame brake rocker arm (5), and the other end links to each other with trailer parking brake lever (11) with crossing adjustment hook (10).Be equipped with one on the parking brake lever (11) and tease and ridicule whole hole, parking brake lever among the figure (11) is in not braking position.
After chaufeur depressed foot brake pedal (not drawing among the figure), main frame lever connection (6) drove rocking arm (5) and swings forward, and main frame is realized braking; While rocking arm (5) drives brake pulling wire (4) again and moves forward in helical steel pipe (1), makes parking brake lever (11) forward swing, trailer braking protection valve pull bar (12) reach, and trailer is also realized braking.
Claims (3)
1, a kind of self-propelled vehicle mechanical type synchronous braking device, particularly be applicable to the mechanical type synchronous braking device on small four-wheel tractor and other equipment of small motor car owner, the trailer, this device comprises a helical steel pipe (1) of bending arbitrarily, a brake pulling wire (4) that passes in it, it is characterized in that having a helical steel pipe (1) of bending arbitrarily, pass a brake pulling wire that can move forward and backward (4) in it, its outer oil resisting rubber hose (2) that is surrounded by.
2, device according to claim 1 is characterized in that helical steel pipe (1) two ends are dragged permanent seat (3), (8) on the thick stick (9) fixing by main frame axle shaft housing (7) and trailer respectively.
3, device according to claim 1 and 2 is characterized in that brake pulling wire (4) one ends link to each other with main frame brake rocker arm (5), and the other end links to each other with trailer parking brake lever (11) by adjusting hook (10).
