Abstract
The utility model relates to a hydraulic brake for bicycles, which is composed of a brake master cylinder, oil pipes, brake sub cylinders and a brake sheet, wherein, the brake master cylinder is composed of a brake handle, a push rod, a fixed frame and a cylinder body and is installed on a handle bar; each of the brake sub cylinders is composed of a cylinder body, a cylinder cover, a speed reducing support frame, a fixed friction sheet and a movable friction sheet, and the brake sub cylinders are installed on a front and a back cross beams of a bicycle frame; the brake sheet is installed on a hub of a bicycle wheel and between the fixed and the movable friction sheets. The master cylinder and the sub cylinders are communicated by the oil pipes, and brake fluid is fully filled into the cylinder bodies. When a bicycle is braked, a brake handle is pressed to push the push rod, the push rod pushes a master cylinder piston to apply brake pressure to the brake fluid, and the brake pressure is transferred to sub cylinder pistons through the oil pipes to push the pistons to drive the movable friction sheet to tightly clamp the brake sheet, so that a bicycle wheel can stop rotating.
Description
The utility model relates to the drg of non-power-driven vehicle.
Bicycle in the past adopts friction members such as rubber, asbestos, steel column, by mechanical transfer pressure such as lever, steel wires, makes friction element compress rim, axletree or propeller boss, reaches the braking purpose.The transmission of pressure resistance is bigger, and deceleration and stopping performance is relatively poor, and part is fragile.Along with the development of bicycle, later-model derailleur, mountain bike are asked the city, and the speed of a motor vehicle is higher, and traditional brake equipment can not satisfy the brake request of new bicycle.
The purpose of this utility model is that a kind of deceleration and stopping performance of proposition is good, and brake is flexible, robust new bicycle brake equipment.
The hydraulic bicycle lock that the utility model proposes according to hydraulic principle, adopts Hydraulic Pump, transmits pressure by braking liquid, drives friction lining, compresses brake pad, makes the bicycle brake of advancing.This brake equipment by master brake cylinder 41, oil pipe 10, brake cylinder 42, brake pad 33, moving, decide Friction disk 24,23 and form.It is characterized in that master brake cylinder 41 is fixed on the handlebar by fixed mount 4, brake cylinder 42 is fixed on the forward and backward fork beam of vehicle frame by shock bracket 35, brake pad 33 is fixed on the propeller boss of wheel, and is inserted in moving, deciding between the friction lining 24,23 of brake cylinder 42.Master brake cylinder 41, brake cylinder 42 are communicated with by oil pipe 10.
Brake cylinder is by the wheel cylinder pump housing 40, and wheel cylinder lid 21 is formed.Hydraulic actuating cylinder 41, the oil transportation mouth of pipe 8, oil duct 11, aie escape valve 19 are arranged on the wheel cylinder pump housing 40.Wheelcylinder piston 32 is housed in the hydraulic actuating cylinder 41, piston 32 1 ends are with O-ring seal 31, and the other end contacts with main shaft 29, is with pull back spring 30 on the main shaft 29, the other end passes catch 28, back-up ring 27, fixed mount 25, and is connected with movable friction plate 24, cushion rubber bumper 26 with screw.The oil transportation mouth of pipe 8 is connected with oil pipe 10 by transport pipe joint 9, and communicates with hydraulic actuating cylinder 41 by oil duct 11.Be fixed with on the wheel cylinder lid 21 and decide friction lining 23.It is corresponding with movable friction plate 24 to decide friction lining 23, and certain clearance is left in the centre, so that put into brake pad 33.
The hydraulic bicycle lock reaches brake cylinder to the pressure of master brake cylinder by braking liquid, by the piston actuated movable friction plate, clamps brake pad, and the transmission of pressure loss is little, and deceleration and stopping performance is good.Brake pad is the bigger disk of diameter, and lock torque is greater than backpedalling brake, band-type brake, the lock that rises, and does not resemble rim easy to wear the rim brake simultaneously again.Be installed on mountain bike, the derailleur can with the variable gear symmetry, not only attractive in appearance but also make safety by bike.
Description of drawings and embodiment:
Fig. 1 is a master brake cylinder;
Fig. 2 is a brake cylinder;
Fig. 3 is a shock bracket;
Fig. 4 is a hydraulic bicycle lock overall diagram.
Embodiment: this hydraulic bicycle lock is processed into the master cylinder pump housing 7 by metallic material through casting, turning, and the wheel cylinder pump housing 40 is installed non-return valve 14 in the master cylinder pump housing 7, and total pump piston 5, push rod k2, brake lever 1 are assembled into master brake cylinder 41.Wheelcylinder piston 32, axis 29, pull back spring 30, catch 28, back-up ring 27, fixed mount 25 are installed in the wheel cylinder pump housing 40, with screw movable friction plate 24, cushion rubber bumper 26 are fixed on the axis 29 then, be fixed on the wheel cylinder lid 21 deciding friction lining 23 with screw again, be assembled into brake cylinder 42.Master brake cylinder 41 is installed on the handlebar by fixed mount 4 and screw, and brake cylinder 42 is connected with shock bracket 35 by connecting panel 20, and is installed on the forward and backward of bicycle rack by shock bracket 35 and sticks.Brake pad 33 is installed on the wheel propeller boss, and inserts and move, decide in the gap of friction lining 24,23.The two ends of oil pipe 10 and oil connector 9 are connected with the oil transportation mouth of pipe 8 of master brake cylinder 41 and brake cylinder 42 respectively.Inject braking liquid, the aie escape valve 19 of screwing on after filling with, pressure regulation oiling bolt 18 from oil hole 17.
During bicycle running, the brake pad 33 that is installed on the wheel propeller boss rotates synchronously with wheel.During brake, press brake lever 1, promote push rod 2, push total pump piston 5 inwards, the hydraulic actuating cylinder 43 interior brake fluid pressures of master brake cylinder 41 are increased and the generation brake-pressure, brake-pressure is in oil pipe 10 is passed to the hydraulic actuating cylinder 44 of brake cylinder 42, and promotion wheelcylinder piston 32, makes friction lining 24 motions, and clamp brake pad with deciding friction lining, stop wheel, thereby reach the purpose of brake, unclamp brake lever and hold, cancel the pressure of 5 pairs of brakings liquid of total pump piston, pull back spring 30 is wheelcylinder piston 32 pushed home, and drives movable friction plates playback, take-off the brake brake lining 33 by main shaft 29.Simultaneously, apply cut-back pressure, be passed to master cylinder hydraulic actuating cylinder 43, promote total pump piston 5 and reset through oil pipe 10 to braking liquid.
