Abstract
The utility model relates to an electric automobile technical field, concretely relates to double pneumatic-hydraulic brake structure that new energy automobile used is the structure of connecting left and right stopper slave cylinder respectively with original stopper oil pipe parallel state, changes into and directly connects left and right stopper slave cylinder series connection's structure through series brake oil pipe. The double-exhaust hydraulic braking structure is convenient to install, adjust and maintain, and the double-row pneumatic-hydraulic braking structure can improve the installation efficiency, reduce the labor intensity of workers, reduce the manufacturing cost of the electric automobile, achieve the energy-saving effect, improve the braking consistency and balance of the left wheel and the right wheel, and increase the braking balance of the automobile body, the reliability and the service life.
Description
Technical Field
The utility model relates to an electric automobile technical field, concretely relates to double pneumatic-hydraulic brake structure that new energy automobile used
Background
The rear axle of the electric automobile is a main driving part of the electric automobile, power is transmitted to rear wheels through a driving motor and a speed reducer, the rear wheels drive the electric automobile to run, and front wheels of the electric automobile can be used as driven and steering wheels. The existing pure electric automobile driving rear axle is generally braked in a split structure, and is braked separately during service braking, so that the unbalanced braking effect of an automobile body can be increased, the energy consumption of an automobile is improved, the unsafe coefficient is increased, the manufacturing and processing cost of the rear axle can be increased, the subsequent installation and after-sale cost can be increased, and the like.
SUMMERY OF THE UTILITY MODEL
The utility model discloses double pneumatic-hydraulic brake structure aim at of electric automobile overcomes the defect among the prior art, provides a simple structure, and braking effect is high, safe convenient electric automobile transaxle braking structure.
In order to achieve the above purpose, the technical scheme of the utility model is that: the utility model provides a double pneumatic and hydraulic brake structure that new energy automobile used, the structure comprises left brake assembly (1), left axle housing welding assembly (2), gearbox (3), right axle housing welding assembly (4), right brake assembly (5), series brake oil pipe (6).
The structure changes the original structure that the brake oil pipes are connected in parallel with the left brake sub pump and the right brake sub pump respectively into the structure that the left brake sub pump and the right brake sub pump are directly connected in series through the series brake oil pipes (6).
The utility model has the advantages and beneficial effect that double pneumatic-hydraulic brake structure is convenient for install, adjustment and maintenance, double pneumatic-hydraulic brake structure both can improve the installation effectiveness, alleviates workman intensity of labour, can reduce electric automobile's manufacturing cost again, can also reach energy-conserving effect, and the uniformity and the equilibrium problem of wheel braking about improving simultaneously increase automobile body braking equilibrium, reliability and life.
Drawings
The invention will be described in detail with reference to the accompanying drawings and examples
FIG. 1 is the overall structure diagram of the present invention
FIG. 2 shows the left brake assembly of the present invention
FIG. 3 shows the right brake assembly of the present invention
Detailed Description
The structure is composed of a left brake assembly (1), a left axle housing welding assembly (2), a gearbox (3), a right axle housing welding assembly (4), a right brake assembly (5) and a series brake oil pipe (6) as shown in figure 1. The left brake cylinder and the right brake cylinder are connected in series through a series brake oil pipe (6), so that the brake cylinders share one oil way during braking. The balance of braking is improved.
As shown in fig. 2, a left brake assembly (1) adopts a brake cylinder (7) with a double oil pipe interface, an upper oil pipe interface is connected with an oil inlet pipe, and a lower oil pipe interface is connected with a serial brake oil pipe (6); the right brake assembly (5) adopts a single oil pipe interface brake cylinder (8), the oil pipe interface is connected with a brake oil pipe (6) in series, and an exhaust valve is arranged on the cylinder and used for exhausting the brake oil pipe.
Claims (2)
1. The utility model provides a double pneumatic and hydraulic pressure that new energy automobile used suppresses structure which characterized in that: the structure comprises left brake assembly (1), left axle housing welding assembly (2), gearbox (3), right axle housing welding assembly (4), right brake assembly (5), series brake oil pipe (6).
2. The double-row pneumatic-hydraulic brake structure for the new energy automobile as recited in claim 1, wherein the left brake assembly (1) adopts a double-oil-pipe-interface brake cylinder (7), and the right brake assembly (5) adopts a single-oil-pipe-interface brake cylinder (8).
