The purpose of this utility model is to provide the motorcycle hydraulic anti-lock device of a kind of simple in structure, good airproof performance, high safety.
The technical solution adopted in the utility model is:
The motorcycle hydraulic anti-lock device, comprise housing, oil inlet and oil outlet, oil inlet is connected with master cylinder, oil outlet is connected with wheel cylinder, be provided with the inner chamber perpendicular in the housing with oil outlet, inner chamber is divided into oil pocket and control chamber, oil pocket is established a shoulder, path has piston rod in the chamber, the piston rod rear end is connected with piston by the shaft shoulder, the shaft shoulder is provided with seal ring oil pocket and control chamber is sealed fully, the other end of piston is by the spring top clamping that is located in the control chamber, and spring can be by the adjustable bolt adjustment, and chamber, the big footpath of described oil pocket communicates with oil inlet, and be arranged on the same axis, the piston rod front end has a conical sealing block, piston rod, piston and cone seal piece are integral, and sealing block is positioned at the shoulder of oil pocket, its circular cone has the diameter of seal oil chamber path accent portion, and the total length that the sealing of circular cone sealing block is moved is less than the length of piston nose to control chamber.
Be provided with a spring seat cushion between the spring in described piston and the control chamber, the spring seat cushion diameter is greater than diameter of piston, by spring top clamping at the control chamber front end.
Described adjustable bolt is provided with a jam nut, and the aft end face of jam nut front end face and housing is adjacent to.
Be provided with a spring between described cone seal piece front end face and the oil inlet aft end face.
The utlity model has following advantage: piston rod, piston and cone seal piece are integral, and sound construction is reliable, can be owing to vibration produces the seal failure phenomenon; This device is established the sealing of three places, has reduced by a place, has improved the sealing reliability of anti-lock device; Adjustable bolt is provided with jam nut, can prevent adjustable bolt because of vibration produces loosening phenomenon, thereby guarantee that oil pressure control satisfies the anti-lock requirement, motorcycle safety is travelled; After pressure oil enters oil inlet, directly flow out from oil outlet through oil pocket, oil circuit is simple, and loss of pressure is little; Simple in structure, saved ball sealer, supporting member and sealing arrangement.
Below in conjunction with drawings and Examples the utility model is done step detailed description.
Fig. 1 is the front view of the utility model embodiment.
As shown in Figure 1, the motorcycle hydraulic anti-lock device comprises 1, housing 2, spring 3, adjustable bolt 4, piston 5, oil outlet 6, fuel-displaced seal ring 7, oil inlet 8, oil-feed seal ring 9, cone seal piece 10, piston packing ring 11, jam nut 12, spring seat cushion 13, spring 14, piston rod.Oil inlet 7 is connected with master cylinder, oil outlet 5 is connected with wheel cylinder, described oil pocket has a shoulder, be divided into chamber, big footpath and two chambeies, path chamber, oil inlet 7 communicates with chamber, big footpath, and be arranged on the same axis, cone seal piece 9, piston rod 14 and piston 4 are formed a part, hereinafter referred to as piston piece, cone seal piece 9 is positioned at the shoulder of oil pocket, and oil pressure just often, cone seal piece 9 is positioned at chamber, big footpath fully, pressure oil enters oil outlet 5 from oil pocket, when oil pressure is excessive, overcomes the friction force of spring 2 spring forces and piston 4 and piston packing ring 10 etc., piston piece moves backward, its tapering awl has the diameter of seal oil chamber path accent portion, blocks oil pocket path accent portion, and oil pressure then can not enter oil pocket path chamber.Oil pressure under the combined action of difference of pressure and spring 2, overcomes the friction force of spring 13 spring forces, piston 4 and piston packing ring 10 etc. after descending, and piston piece moves forward.In order to guarantee that piston piece during sway, does not cause whole piston 4 to break away from the path chambeies in the path chamber, can't reset, during circular cone sealing block 9 seal oil chamber path accent portions, required mobile total length must be less than the length of piston 4 front ends to control chamber; When piston packing ring 10 moved with piston 4, its front end should be no more than the oil outlet of oil pocket, produced wearing and tearing or scratch to avoid sealing member in moving process, caused seal failure.
