Content of the invention
For solving the above problems, overcome the deficiencies in the prior art, this utility model provides a kind of safe, braking side
The various hydrostatic 4 wheel driven down-hole special-purpose vehicles brakes of formula.
For achieving the above object, the hydrostatic 4 wheel driven down-hole special-purpose vehicles brakes that this utility model provides, including throttle
Pedal, hydraulic pump, hydraulic motor, operation handle, brake pedal, movable friction plate and static friction piece, parking spring, hand brake lever, wet
Formula brake；It is characterized in that hydraulic pump is connected with electromotor by shaft coupling, electromotor connects also by intermediate connecting rod mechanism
There is the gas pedal controlling engine speed；Operation handle is connected with the swash plate of hydraulic pump by control piper, described hydraulic pump
It is connected with hydraulic motor by pipeline；Wet brake is arranged on drive axle, and the brake cylinder of described wet brake passes through
Piston shaft is connected with static friction piece, and described static friction piece is also associated with parking spring.
Further, gas pedal is deeper, and engine speed is higher, and hydraulic pump flow is bigger, and speed is higher, gas pedal
More shallow, engine speed is lower, and hydraulic pump flow is less, and speed is lower, and gas pedal is lifted completely, and motional inertia reacts on
Drive motor and hydraulic pump, reduce speed；The swash plate angle of hydraulic pump is bigger, and hydraulic pump flow is bigger, when swash plate angle is zero
Hydraulic fluid flow rate is zero, and when swash plate flow is zero, hydraulic motor cannot rotate, and the hydrostatic braking realized by car load.
Further, the piston shaft of described brake cylinder is connected with back-moving spring.
Further, wet brake is connected with hand brake lever and brake pedal by brake cable；Step on brake pedal or draw
Play hand brake lever, the hydraulic oil of wet brake enters in the plunger shaft of brake cylinder, and under oil pressure effect, back-moving spring is pressed
Contracting, static friction piece and movable friction plate are compressed by piston shaft movement, realize braking.
Further, parking spring can promote static friction piece and movable friction plate when when hydraulic system pressure out of hand
Compression, realizes braking.
The beneficial effects of the utility model are：This utility model provides multiple modes of braking, and each mode of braking is separate,
After a kind of mode of braking lost efficacy, do not affect the braking effect of other modes, car load good braking effect, safe and reliable.
