The utility model is acted on backbar 2 to solve the side force of wheel of vehicle, improves the force-bearing situation of backbar 2, knot Auxiliary support 34, second in Auxiliary support 35, first outer Auxiliary support 44, second outer Auxiliary support are additionally arranged in first on structure 45, solve the problems, such as 2 one-sided stress of backbar.

The utility model utilizes the characteristics of hydraulic drive, different using the output of different oil circuits on hydraulic pressure using extrusion principle Pressure, meet the speed governing requirement of different automobile types different braking power.Brake force is produced using the inside and outside braking rail of vehicle crush, had Effect reduces energy consumption, is typical energy-conserving product.

Operation principle of the present utility model is：Vehicle enters reducer track circuit on hump, and control system is as needed After sending brake command, under hydraulic system effect, the utility model mechanical mechanism is started working, in original retarder location.When When vehicle enters decelerator, wheel extruding braking rail (3), hydraulic system and the inside and outside oil cylinder working-pressure of work are increased to setting value, this Pressure passes through inside and outside connecting seat-inside and outside braking rail-and passes to wheel, produces frictional resistance, prevents vehicle movement, makes vehicle Speed declines.When car speed, which reaches control, to be required, control system sends alleviation order, and inside and outside piston rod is retracted, and is driven Inside and outside braking rail moves to alleviating position together on inside and outside connecting seat, and vehicle passes through decelerator.

Utility model works process and mode：

There are three operating positions in the utility model mechanism, by taking the two-sided deceleration system of double track bar non-gravity formula translation as an example, one Individual is original retarder location, i.e., the inside and outside inside and outside oil cylinder of decelerator stretches out, and now two inside and outside braking rail friction interplanar distances are 128₀ ⁺³ mm.Another is working position, i.e., vehicle enters the positive position for implementing braking after decelerator brake actuator, now passes through wheel It is 128 to extrude two inside and outside braking rail friction interplanar distances₀ ⁺³After mm openings, the spacing of two inside and outside braking rail rubbing surfaces is equal to wheel Thickness.3rd position is to alleviate working position, i.e., position when wheel passes through decelerator, and now inside and outside oil cylinder is retracted, in two, Outer braking rail rubbing surface institute spacing is 165₀ ⁺³mm。

The conversion of the utility model brake rating.The utility model coordinates with multistage or stepless speed reducer hydraulic system and made With.Needed that vehicle can be implemented the braking of different stage according to control system.When brake rating is changed, the mechanical-like of executing agency State is constant, and simply inside and outside oily in-cylinder pressure size can need to change according to control command.Brake rating conversion speed is in number In Millisecond, the high requirement of decelerator control accuracy is adapted to.

In actual applications, single-rail deceleration system is arranged on unilateral stock rail the present invention by 5-7 section decelerator units Combine.According to yard needs, single-rail deceleration system can be connected into, as shown in Figure 1.Decelerator can also be saved by 5-7 Unit is left and right symmetrically arranged on stock rail, connects into double track bar deceleration system as shown in figure 4, to adapt to different occasion needs.

Above content is to combine specific preferred embodiment further detailed description of the utility model, it is impossible to Assert that specific implementation of the present utility model is confined to these explanations.For the ordinary skill of the utility model art For personnel, without departing from the concept of the premise utility, some simple deduction or replace can also be made, should all be regarded To belong to the scope of protection of the utility model.
