Description
The utility model relates to bicycle.
The mountain bike in past, owing to will ride on complex-terrains such as mountain area, die Dorfstrasse, its tire tread is thick, vehicle frame and front fork are rough strong.This mountain bike tire friction force is big, and is whole sturdy and durable, good rigidly.But its vibration is big, and vibrationproof is poor, and is extremely uncomfortable when riding.
The purpose of this utility model is to overcome above-mentioned shortcoming and defect, provides a kind of both sturdy and durable, has big friction force and high intensity to ride to adapt to the mountain region, vibrates for a short time again, favorable damping is arranged and the mountain bike of traveling comfort of riding.
In order to achieve the above object, the utility model mountain bike is by vehicle frame, be installed in the front fork on the preceding pipe of vehicle frame, be installed in the handlebar on front fork top, be installed in the preceding spindle unit of front fork lower end, front-wheel before being installed on the spindle unit, be installed in the saddle on the standpipe of vehicle frame, be installed in the rear axle part of the chain stay lower end of vehicle frame, be installed in trailing wheel and flywheel on the rear axle part, be installed in the axis parts on the center tap of vehicle frame, be installed in the sprocket wheel on the axis parts, be installed in crank and pedal on the axis parts, be installed in the chain on sprocket wheel and the flywheel, the front and rear brake that is installed on front fork and the vehicle frame constitutes.Vehicle frame by former pipe, go up pipe, the shock absorber between the preceding spider, the chain stay that constitute of pipe, standpipe and center tap welding and the following pipe lower end that is installed in chain stay upper end and preceding spider is constituted down.Chain stay is linked to each other with left and right chain stay leg with screw with right chain stay leg, two ends by the left chain stay leg of its upper end weld together and constitutes with the support of the chain stay of standpipe solder together.
Shock absorber by the lower adaptor of the following pipe lower end that is welded on vehicle frame, be welded on the chain stay upper end top connection, with screw be fastened on guide pillar in the top connection, be fixed in the lower adaptor and insert the fixing screw that plays the role of positioning in the axis hole of guide pillar bottom, the compression spring that is sleeved on the guide pillar is constituted.
When riding, when trailing wheel runs into when playing on the obstacle, rear axle part pops up chain stay.Chain stay is supported for fulcrum with chain stay, and the chain stay upper end just moves downward, and then the compressing top connection, compression spring is further compressed again.Compression spring was inhaled and was store a part of kinetic energy this moment, had avoided vehicle frame single-piece severe jolt, had played damping of vibrations.When trailing wheel restored, compression spring moved the chain stay upper end gently on chain stay supports.Reset also quite steady this moment.
Shock absorber also can be the hydraulic damping shock absorber.It is by the top connection of the chain stay upper end that is welded on vehicle frame, be installed in the last dust protecting cap in the top connection, be welded on the damper base of down tube lower end, the lower adaptor that is connected with damper base with bearing pin, be installed in the lower adaptor and be sleeved on following dust protecting cap in the dust protecting cap, be connected in the oil cylinder in the top connection, be connected in the lower adaptor and the other end in-oil cylinder piston rod of packing into, be connected on the piston rod other end and have the piston of damping hole, pack into hydraulic oil in the oil cylinder, be installed between top connection and the lower adaptor and be sleeved on piston rod and compression spring that oil cylinder is outer and be installed in oil cylinder and piston rod between oil sealing constitute.
The effectiveness in vibration suppression of hydraulic damping shock absorber is better than aforementioned compression spring shock absorber.When jumping on the trailing wheel, the chain stay upper end falls, and top connection is depressed, and the compression spring in the hydraulic damping shock absorber is compressed.Meanwhile, piston rod moves on relatively in oil cylinder together with piston, and the hydraulic oil in the oil cylinder epicoele is compressed, and slowly leaks into from the damping hole of piston in the cavity of resorption of oil cylinder, and compression spring moved down generation shock damping action, energy storage, vibration damping simultaneously.When moving on the chain stay upper end, piston moves down relatively, the compression spring elongation, and hydraulic oil enters epicoele through damping hole from the cavity of resorption of oil cylinder, also produce shock damping action, vibration damping simultaneously.
The left and right sides leg of front fork can adopt shock absorber equally, and jounce bumper for example is so that the front-wheel vibration damping.The jounce bumper of front fork can adopt the structure of above-mentioned compression spring shock absorber, also can adopt the structure of motor bike or some commercially available morpet.
Flywheel and sprocket wheel can be multistage, also can be single-stages.For multistage flywheel and multi-chain gear wheel, on vehicle frame, install rear derailleur and front chain shifter additional, on handlebar, install back controller and preceding controller additional.This has been known prior art all.
Task of the present utility model comes to this and finishes.
The utility model has the favorable damping performance, and it is steadily comfortable to ride.It had both kept the mountain bike wide base tire, the thick power of crown decorative pattern, and friction force is big, and car body strength height, robust advantage have overcome again and have vibrated big, the uncomfortable shortcoming of riding.It can be widely used in ride ride instead of walk, in the activity such as sport and body-building and match amusement.
Below in conjunction with embodiment and accompanying drawing thereof the utility model is done further explanation.
Fig. 1 is the structural representation of embodiment 1.
Fig. 2 is the structural representation of embodiment 1 hydraulic damping shock absorber.
Fig. 3 is the structural representation of embodiment 2 compression spring shock absorbers.
Fig. 4 is the structural representation of embodiment 3 air damping shock absorbers.
Among Fig. 1, embodiment 1 is made of vehicle frame 1, front fork 2, handlebar 3, preceding spindle unit 4, front-wheel 5, saddle 6, rear axle part 7, trailing wheel 8, flywheel 9, axis parts 10, sprocket wheel 11, crank 12, pedal 13, chain 14, front and rear brake 15.Vehicle frame 1 by former pipe 16, on manage 17, manage 18 down, preceding spider peace fork 21, shock absorber 22 that standpipe 19 and center tap 20 are welded constitute.On the chain stay 21 with screw 23 fastening the chain stay that links to each other with left and right chain stay leg support 24.Shock absorber 22 is the hydraulic damping shock absorber.Also have jounce bumper 38 on the front fork 2.
Shown in Figure 2, the hydraulic damping shock absorber by the lower adaptor 28 that is welded in top connection 25 on the chain stay 21, is welded in damper base 26 on the down tube 18, links to each other with damper base 26 with bearing pin 27, go up dust protecting cap 29, dust protecting cap 30, oil cylinder 31, piston rod 32, the piston 34 that has damping hole 33, hydraulic oil 35, compression spring 36, oil sealing 37 constitute down.
