Abstract
The utility model provides an automobile auxiliary brake device, comprising a shoe frame, a pump, a shoe head and a friction plate. The pump is fixed on an automobile girder which is arranged at the front side or the rear side of rear wheels by the shoe frame; the head of the pump rod is fixed with the shoe head; the bottom of the shoe head is provided with the friction plate which is corresponding to the ground. When the automobile auxiliary brake device is in use, the pump rod pushes and presses the shoe head of the head thereof; the friction plate at the bottom of the shoe head flatly presses on the road surface and leads a friction force to be generated between the friction plate and the ground, thus having a braking effect; the automobile auxiliary brake device has greatly reduce the accident incident, reduces the personal injury and death and property loss and improves the safety performance of the automobile.
Description
Technical field
The utility model relates to a kind of brake gear, is meant a kind of auxiliary automobile braking device especially.
Background technology
Existing automobile generally only is provided with a cover brake system, and it adopts oil pressure or air pressure to realize brake usually, not other assist brake means.If the oil circuit of brake system, gas circuit take place to stop up or leak, the malfunctioning or brake weight of brake system is weakened, thereby braking distance is elongated, beyond taking place easily; In addition, overspeed driving car, the loading carrying is descended the abrupt slope continuously or is gone down the hill, and very easily bumps or overturns, if brake failure allows the people feel simply helpless especially.The brake gear of therefore existing automobile self can not satisfy the requirement of safety shut-down fully.
Summary of the invention
Problem to be solved in the utility model is, overcomes the deficiency of above-mentioned technology, and a kind of auxiliary automobile braking device that can guarantee braking automobile safety is provided.
The technical scheme that its technical matters that solves the utility model adopts is as follows: auxiliary automobile braking device, it is characterized in that forming and comprise boot of elevator, pump, boots head, friction lining, described pump is fixed on the automotive frame of trailing wheel front side or rear side by boot of elevator, the head of its pump rod is the boots head fixedly, friction lining is installed in described boots head bottom, and this friction lining is corresponding with ground.
This auxiliary automobile braking device is at least respectively adorned in the vehicle right and left both sides, and for reaching better braking effect, the left and right sides can be adorned many.
The beneficial effects of the utility model are as follows: during the utility model work, pump rod pushes the boots head of its head, the friction lining concora crush of boots head bottom is on the road surface, make between friction lining and the ground and produce friction force, thereby play braking action, this auxiliary automobile braking device can reduce accident rate greatly, reduces personal casualty and property damage, improves the safety performance of automobile.
Description of drawings
Fig. 1 is the utility model auxiliary automobile braking device master TV structure figure.
The specific embodiment
With reference to the accompanying drawings and in conjunction with the embodiments the utility model is described in further detail.But the utility model is not limited to given example.
As shown in Figure 1, the utility model auxiliary automobile braking device, its composition comprise boot of elevator 2, pump 4, boots head 6, friction lining 8, pump 4 is fixed on the automotive frame 1 of trailing wheel rear side by boot of elevator 2, the head of its pump rod 7 is boots head 6 fixedly, and friction lining 8 is installed in boots head 6 bottoms, and this friction lining 8 is corresponding with ground.Not enough as installing space, pump of the present utility model also can be installed on the crossbeam of trailing wheel front side.Pump 4 of the present utility model can be selected air lift pump or Hydraulic Pump for use.
As shown in Figure 1, in this enforcement, pump 4 is captiveed joint with boot of elevator 2 by clevis bolt 3; Pump rod 7 is captiveed joint by attachment pegs 5 with boots head 6.
In order to reach good assist brake effect, in the present embodiment, the angle α that pump rod 7 stretches out direction and automobile working direction is an acute angle, and its best angle scope is [50 °, 80 °].
Pump of the present utility model can be provided with 4 gears, and neutral is to hang shelves, boots head ground Clearance maximum; 1 grade is half suspension shelves, to reduce ground Clearance and anxious stopping the reaction time; 2 grades is the anxious shelves of stopping; 3 grades is the lifting shelves, can rise tire liftoff so that vehicle maintenance and repair.Neutral, 1 grade, 3 grades are by manual control.The auxilliary anxious pedal of stopping of stopping is installed in by the main pedal of stopping and the main parallel connection of stopping.Slowly stop and have only main stopping to work, then main before this stopping of suddenly stopping worked, and is that auxilliary stopping worked again, can make brake steadily like this.After the auxilliary brake, pump rod pushing boots head, boots are followed with after the road surface contact, and the friction lining concora crush makes the increase of friction lining pressure on the road surface, play braking action.During manipulation, run into auxilliary the stopping in smooth-riding surface and manually put into 1 grade,, be convenient to anxious stopping to reduce the ground Clearance.Run into roughness pavement, the speed of a motor vehicle is slower, does not need to stop with auxilliary, and therefore auxilliary stopping manually put into neutral.
The utility model boots head width is more than or equal to tyre width, and length can be lacked, and the gross area that the gross area that friction lining contacts with the road surface contacts with the road surface greater than tire on the drive wheels, pump can provide enough pressure again, so the auxilliary effect of stopping can be better than the main effect of stopping.
Because friction lining and wear on tyres, the relative position of pump and crossbeam will constantly be aligned with the levelling nut.
Claims (8)
1, auxiliary automobile braking device, it is characterized in that composition comprises boot of elevator, pump, boots head, friction lining, described pump is fixed on by boot of elevator on the automotive frame of trailing wheel front side or rear side, and the head of its pump rod is the boots head fixedly, friction lining is installed in described boots head bottom, and this friction lining is corresponding with ground.
2, auxiliary automobile braking device according to claim 1 is characterized in that described pump captives joint with boot of elevator by clevis bolt.
