The specific embodiment
A kind of four-wheel electric motor car brake gear as shown in Figures 1 to 4, comprises brake pedal 1, pedal shaft 10, brake compensation piece 12, brake pump 4, adapter plate 3, brake pump connecting rod 7.
Be fixed with braking top board 2 and braking on the pedal shaft 10 hangers 11 is installed.Brake compensation piece 12 is installed hangers 11 by braking hook and braking and is connected, and the brake cable pull of vehicle rear wheel is connected with brake compensation piece 12.When pedal shaft 10 rotates, thereby drive braking the brake cable pull that hangers 11 rotates the tension trailing wheel is installed, brake cable pull is connected with the braking execution unit of trailing wheel, realizes the braking of trailing wheel.
The oil cylinder of brake pump 4 is connected with the front wheel brake execution unit by oil pipe line.The piston rod 5 of brake pump 4 connects as one by adjusting screw rod 14 and adjustment nut 6 and brake pump connecting rod 7.Be equiped with the zanjon roller bearing in the end of brake pump connecting rod 7 and hold 8, its position adapts with braking top board 2, make when pedal shaft 10 drive braking top boards 2 rotate forward, braking top board 2 holds 8 and promote to formulate pump rod 7 and brake pump piston rod 5 moves forward near the zanjon roller bearings, brake pump 4 work, discharge pressure oil is realized front wheel brake.
Piston rod 5 and brake pump connecting rod 7 are installed on the adapter plate 3, and adapter plate 3 is fixed on the hull.As shown in Figure 3, Figure 4; brake pump connecting rod 7 and brake pump piston rod 5 are enclosed within the fixed block 13; fixed block 13 is by in the mounting hole that is bolted to adapter plate 3; the operation scheme that has guaranteed brake pump connecting rod 7 and brake pump piston rod 5 like this be before straight straight after; can not occur being partial to up and down; not only good braking effect also can be protected brake pump 4, prolongs the service life of brake pump.The cross-sectional plane of brake pump connecting rod 7 is non-circular, as the shape of polygon, semicircle, ellipse or other non-circles.And the shape of the mounting hole of the mounting blocks 13 of installation slipper connecting rod 7 and the shape of cross section of brake pump connecting rod 7 adapt, and can prevent that preceding brake pump connecting rod 7 from rotating by actv. in the hole like this, and it can only directly be moved front and back, make the maximizing efficiency of transmission.As shown in Figure 4, the total length of brake pump connecting rod 7, brake pump piston rod 5 and adjustment screw rod 14 can be regulated by nut 6, when the front and rear wheel that causes because of reasons such as brake pumps is braked the disunity problem, can regulate the total length head it off by adjustment nut 6 after battery-driven car uses a period of time.Adjusting the two ends of screw rod 14 stretches into respectively in the end centre hole of piston rod 5 and brake pump connecting rod 7, and adjustment screw rod 14 two ends respectively are equiped with an adjustment nut 6 and are close to piston rod 5 free-ended end faces and brake pump connecting rod 7 one end end faces respectively, can change the length of adjusting in the end centre hole that screw rod 14 stretches into piston rod 5 or brake pump connecting rod 7 by rotating one of them adjustment nut 6, thereby change brake pump connecting rod 7, brake pump piston rod 5 and adjust the total length of screw rod 14.Adjusting during for ease of maintenance, the position over against adjustment nut 6 on adapter plate 3 offers window 15, is convenient to regulate adjustment nut 6 with spanner below hull.
Above-mentioned brake gear glancing impact after brake pedal 1 is operated, drives pedal shaft 10 rotations, and pedal shaft 10 drives braking installation hangers 11 simultaneously and braking top board 2 rotates forward.At this moment, braking is installed hangers and is compressed back brake compensation piece 12, brake cable pull, realizes that the machinery of trailing wheel is formulated; Simultaneously, rotate top board 2 promotion brake pump connecting rods 7 and brake pump piston rod 7 and travel forward, brake pump 4 stressed discharge brake solution realize the oil brake of front-wheel.
Braking is installed hangers 11 and is braked the same position that top board 2 can be installed in pedal shaft 10, also can be installed in the different parts of pedal shaft 10 according to hull structure needs, or same position forms different angles; Perhaps braking is installed hangers 11 and braking top board 2 and is made an integral body and be connected with pedal shaft 10, but has the position that spurs the trailing wheel brake cable pull simultaneously and the position of promotion front wheel brake sucker rod.
Above content be in conjunction with concrete preferred implementation to further describing that the utility model is done, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, under the prerequisite that does not break away from the utility model design, can also make some simple deduction or replace, all should be considered as belonging to protection domain of the present utility model.
