Description
Technical field
The utility model relates to automotive field, relates in particular to a kind of Vehicular brake device.
Background technology
Brake system is the necessary system that vehicle safety ensures, brake system be on automobile with so that extraneous (being mainly road surface) applies certain power in some part of automobile (being mainly wheel), thereby it is carried out to a series of special arrangements of forced brake to a certain degree.
Brake system effect is that the automobile in making to travel carries out forced deceleration according to the requirement of chaufeur and even stops; Make the automobile of stagnation of movement under different kinds of roads condition, (be included on ramp) steadily halt; Make the car speed of descent run keep stable.
Service brake---handled with pin by chaufeur, therefore claim again foot brake system.Its function is make car deceleration just under steam or stop in the shortest distance.Though braking during standstill system handles with hand by driving, therefore claim again hand braking system.Its function is to make to be parked in the resident secondary brakes as you were of automobile on various road surfaces in the situation that of driving brake-system failure, ensures that automobile still can realize a covering device that slows down or stop.In the brake legislation of many countries, specify, secondary brakes is also that automobile is prerequisite.The automobile that auxiliary brake system travels through the mountain area of being everlasting and the automobile of some special purpose, in order to improve the safety of driving and to alleviate the decline of service brake performance and the wearing and tearing of drg, in order to stabilizing speed when the descending.
Brake gear is by producing friction between brake facing and wheel hub or disc, and the kinetic energy during by running car is transformed into thermal energy consumption and falls in the process of friction.Common brake gear has " drum brakes " and " disk type brake " two kinds of patterns.
One, drum brakes:
At two semi-circular brake facings of wheel hub the inside installing, utilize " lever principle " to promote brake facing and make brake facing contact and rub with wheel hub inner face.
Two, disk type brake:
Remove to clamp the braking disc on wheel with two brake facings of brake callipers control.In the time that brake facing is clamped disc, its two can produce friction.
Drum brakes has been applied in above automobile nearly centurial history, but due to its reliability and powerful braking force, makes drum brakes still be configured in many vehicles and (be used in trailing wheel more) now.Drum brakes is will be installed on brake facing in brake drum toward extrapolation by hydraulic pressure, make brake facing with along with face within the brake drum of vehicle wheel rotation rubs, and produce the effect of braking.
The brake drum inner face of drum brakes is exactly the position that brake gear produces brake torque.In the situation that obtaining identical brake torque, the diameter of the brake drum of drum type braking device can be also little more many than the brake disc of disk type brake.Therefore the full size vehicle that load-carrying is used is to obtain powerful braking force, is merely able to install drum brakes among the finite space of wheel rim.
Due to performance and moving velocity and the hurriedly increasing of day of vehicle, be to increase the stability that vehicle brakes in the time running at high speed, disk type brake has become the main flow of current brake system.Because the brake disc of disk type brake is exposed in air, make disk type brake have good thermal diffusivity, when vehicle does sudden stop or repeatedly brake at short notice at fast state, the performance of brake is difficult for decline, can allow vehicle obtain preferably braking effect, to promote the safety of vehicle.
But, corresponding full size vehicle, especially large engineering vehicle, such as mining large engineering vehicle is widely used in the field such as mine, capital construction, because its road conditions of travelling are poor, load carrying ability is large, also corresponding higher to the brake request of vehicle, and in mining area, road conditions are disliked slightly, heavy grade road conditions are more, thus the braking during standstill ability of standard can not meet heavy grade stop requirement, affect vehicle reliability, safety.
Utility model content
Many aspects of the present utility model provide a kind of Vehicular brake device, can improve mine car in the more difficult problem of heavy grade parking.
One side of the present utility model, a kind of Vehicular brake device is provided, that described Vehicular brake device comprises is antitorque after output flange after change speed gear box, drum brake mechanism, rear propeller shaft, vehicle frame, balanced thrust force frame, calliper, brake disc, brake support frame, rear-axle casing, wherein, described drum brake mechanism is connected with output flange after described change speed gear box, described calliper is connected with described rear-axle casing, described drum brake mechanism and described calliper act on described rear propeller shaft by hydraulic efficiency pressure system simultaneously, realize the braking during standstill of vehicle.
Preferably, described calliper is arranged on described rear-axle casing and back axle input flange.
The Vehicular brake device of foregoing description, can be applicable to travel at the poor large engineering vehicle of the railways and mineies such as hill path, mining area, drum brake mechanism is combined with calliper, pass through fluid control, it is braked simultaneously, can improve mine car in the more difficult problem of heavy grade parking.
Brief description of the drawings
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is embodiment more of the present utility model, for those of ordinary skill in the art, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is a kind of Vehicular brake device structural representation of the utility model one embodiment.
Detailed description of the invention
For making object, technical scheme and the advantage of the utility model embodiment clearer, below in conjunction with the accompanying drawing in the utility model embodiment, technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is the utility model part embodiment, instead of whole embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.
As shown in Figure 1, be a kind of Vehicular brake device structural representation of the utility model one embodiment, described Vehicular brake device can be applicable to travel at the poor large engineering vehicle of the railways and mineies such as hill path, mining area.
