Abstract
The utility model relates to a service brake system for a forward-tipping cab-over-engine truck. In the service brake system, a master brake cylinder is mounted on a cross beam of an automobile close to an air storage tank so as to reduce the length of a pipeline; a control part of the master brake cylinder is hinged with a brake arm mounted at the front end of the cross beam through a connecting rod, and the other extending end of the brake arm is hinged with a brake pedal arm on a cab; and the brake pedal arm is fixedly connected with the a brake pedal. With the adoption of the structure, the space in the cab is increased, and the length of the pipeline is reduced, so that the brake reaction is quicker and the braking is reliable and safe.
Description
Technical field
Automobile pneumatic braking system class belongs to the down tilt head lorry service braking system that leans forward concretely.
Background technology
It is indoor that present traffic-type truck aerodynamic brake master cylinder all is mounted in the vehicle drive of cab-over-engine vehicle, and master cylinder is got the wheel cylinder that gas leads to front and back wheel from two storage tanks respectively.Because end spaces is little before the traffic-type truck operator's compartment, be again driving engine below the operator's compartment, the parts that are installed in now in the operator's compartment are more and more again.Make the mechanical control structure of master cylinder and master cylinder difficulty is installed or, cause potential safety hazard to making operation inconvenience.Need tumble forward when safeguarding because of operator's compartment in addition, four pipelines of turnover master cylinder all can be used India rubber tube, and its shortcoming is near the engine temperature height, make it aging easily.Secondly, this structural joint is many, has increased the gas leakage point, and pipeline is long again, make the brake reaction time corresponding slack-off, especially back axle need be braked earlier than propons for the security consideration back axle, and this structure is to making the back axle pipeline long more a lot of than propons, and reacting phase should be slack-off, is unfavorable for safe driving.
Summary of the invention
For overcoming above deficiency, the utility model will solve its technical matters and be to provide a kind of down tilt head lorry service braking system that leans forward, this system is installed in master cylinder near on the automotive frame of storage tank, reduce the length of pipeline, master cylinder is by the control of metal linkage, both reliable, safety again.
The technical scheme that its technical matters that will solve the utility model adopts is: master cylinder is installed near on the automotive frame of storage tank, two air chambers of master cylinder are got gas from storage tank separately respectively, by the wheel cylinder of valve member Control of Automobile propons and back axle, this part is consistent with the bonneted truck brake system respectively for the air extractor duct of master cylinder.The master cylinder control part is hinged with the brake arm that is installed in the crossbeam front end by connecting rod, and the brake pedal arm that brake arm stretches out on an end and the operator's compartment in addition is hinged, and brake pedal arm and brake pedal are affixed.Wherein pivotally attached brake pedal arm at least also has a face to contact with brake arm in addition.This kind structure brake pedal when operator's compartment is tumbled is tumbled together, and sensation brake pedal and brake arm are affixed when chaufeur is trampled brake pedal.
Beneficial effect is that brake pedal is installed easily, increases to drive the interior space, reduces pipeline length, and the brake reaction is faster, has reduced pipe joint, reduces aging.Vehicle safety travel largely depends on the superior of deceleration and stopping performance, therefore increases the safety factor of a little, also is worth.
Description of drawings
Fig. 1 is that the utility model brake pedal is at the indoor position block diagram of vehicle drive;
Fig. 2 is a master cylinder control setup planar view.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
As shown in Figure 1, 2: operator's compartment (1), brake pedal (2), crossbeam (3), brake pedal arm (4), assist brake protruding (5), hinge pin (6), brake arm (7), connecting rod (8), master cylinder (9).
Master cylinder (9) is installed near on the automotive frame (3) of storage tank, two air chambers of master cylinder (9) are got gas from storage tank separately respectively, by the wheel cylinder of valve member Control of Automobile propons and back axle, this part is consistent with the bonneted truck brake system respectively for the air extractor duct of master cylinder (9).The control stalk of master cylinder (9) and rod hinge connection are also hinged with brake arm (7) metapore that is installed in the crossbeam front end by connecting rod, brake arm (7) stretch out forward one section with operator's compartment on brake pedal (2) hinged, brake pedal arm (4) is affixed with brake pedal (2), and wherein brake pedal arm (4) has certain camber consistent with brake arm (7) amplitude.
When traveling automobile needs glancing impact, chaufeur is stepped on brake pedal (2) because power be perpendicular to the former brake pedal (2) of brake pedal (2) and affixed brake pedal arm (4) can not and brake arm (7) between rotate.It is affixed with brake arm (7) that just be equivalent to brake pedal (2) this moment.When chaufeur was stepped on brake pedal (2), brake arm (7) pulling connecting rod made master cylinder (9) action, finishes braking.The floor of operator's compartment (1) is just held brake pedal arm (4) and is allowed it rotate counterclockwise around brake arm (7) when operator's compartment (1) need be tumbled.Also have an additional function to allow operator's compartment and brake pedal arm (4) brake pedal (2) when tumbling in operator's compartment, extend exactly, we limit its elongation by assist brake protruding (5), so just be equivalent to chaufeur and touching on the brake equally, force brake arm (7) pulling connecting rod to make master cylinder (9) action.It is the same that we are arranged to the foresight braking effect to this effect, and benefit is need tumble operator's compartment (1) when checking when chaufeur stops car, can reduce some chaufeurs and forget the danger of drawing braking during standstill.Forget the lock jail after operator's compartment lockable mechanism fault or maintenance, operator's compartment (1) is tumbled suddenly in driving procedure, and at this moment assist brake protruding (5) is just given braking force of service brake, reduces dangerous.
Claims (2)
1. the down tilt head lorry service braking system that leans forward is characterized in that: master cylinder is installed near on the automotive frame of storage tank, the master cylinder control part is hinged with the brake arm that is installed in the crossbeam front end by connecting rod, the brake pedal arm that brake arm stretches out on an end and the operator's compartment in addition is hinged, and brake pedal arm and brake pedal are affixed.
2. the down tilt head lorry service braking system that leans forward according to claim 1 is characterized in that: wherein pivotally attached brake pedal arm at least also has a face to contact with brake arm in addition.
