Abstract

The invention discloses an independent suspension mechanism allowing upright hopping of a front wheel of a motor vehicle, as well as a steering mechanism, belongs to the technical field of a chassis of the motor vehicle with two or more wheels, and solves the technical problem existing for a long time that the front wheel of the motor vehicle cannot hop in an upright manner under an independent suspension condition, and the initial upright state of the front wheel can be changed due to the hopping of the front wheel; besides, in the steering mechanism specially arranged for the suspension mechanism, all components are connected through bearings in a sleeving manner, and the technical problem that the steering mechanism relies on a conventional tie rod ball for a long time is solved; and because the problems are solved, the driving stability of the vehicle is facilitated ultimately, the ride comfort is improved, and the load capacity is increased relatively. The technology of the independent suspension mechanism is characterized in that pre-tie fork frames with four bearing positions are arranged, and shaft rods arranged on a vehicle body frame in a penetrating manner is sleeved at a left bearing position and a right bearing position at the front end of each pre-tie fork frame; the axis orientation of suspension bearing sleeves of the shaft rods is the same as the rotation direction of wheels; and shaft rods at the upper ends of pre-tie forks for erecting the wheels are sleeved at the two bearing positions at the rear end of each pre-tie fork frame. The steering mechanism is specially arranged for the independent suspension mechanism.

Description

Independent suspension mechanism and steering mechanism that front wheels of motor-vehicles can upright be beated

Technical field

Patent of the present invention is related to and is applied to front wheel independent suspension and the steering of two-wheeled above motor vehicles use Mechanism

Background technology

Automobile-used front suspension fork mechanism is supported between tire and vehicle body, can relax uneven road surface and pass to car The impact of body, decay therefore the inclination of the left and right, up and down direction of generation, rock and shake, that is, bradyseism effect, To improve the comfortableness of passenger riding, to reduce the abrasion to vehicle for the impulsive force.Automobile-used front suspension is generally divided into three Kind, i.e. independent suspension, semi-independent suspension and rigid axle suspension, independent suspension with respect to rigid axle suspension etc. by Can individually beat in wheel around and mutually directly not be concerned with, thus its travel stability, bradyseism, relax Adaptive preferably, is the hang that Modern Car great majority adopt, but in the independent suspension structure of existing car Vehicle bridge uses breakaway-element, complex structure, and load capacity is limited, is not suitable for the use of other vehicles, As relative a little bigger vehicle of loading capacity etc., conventional vehicle bridge is the jump of wheel in the independent suspension mechanism of breakaway-element Moving can not be upright.

Steering mechanism is the especially setting for this independent suspension mechanism.

Patent of invention content

It is an object of the invention to provide a kind of independent suspension mechanism that can upright beat of front wheels of motor-vehicles and Steering mechanism, it is that a kind of structure is relatively easy, and bearing capacity is relatively preferable, can reach preferable bradyseism, Reduce the independent suspension mechanism rolling, the beating of wheel can be achieved on the upright steering machine beated, provide Structure is relatively slimmer and more graceful and firm and durable.

For solving this technical problem, the technical scheme is that：The suspension that motor vehicles can upright be beated Mechanism and steering mechanism, suspension fork mechanism includes vehicle body frame, hanger bracket and shock absorbing apparatus, and described vehicle body frame is respectively For setting up vehicle body, described hanger bracket includes front chain stay frame and front chain stay, and front chain stay frame is connected with front chain stay, Front chain stay is used for setting up Herba Plantaginis wheel, described shock absorbing apparatus between vehicle body frame and hanger bracket, described hanger bracket bag Include the front chain stay frame of both sides and coupled front chain stay, described vehicle body frame is fixed with support bar and corresponds to Above chain stay frame before two, before described two, between chain stay frame and support bar, it is respectively equipped with shock absorbing apparatus, described Axostylus axostyle is fixed with vehicle body frame, before described two, the connection end of chain stay frame is set on axostylus axostyle by bearing respectively, On chain stay frame before the upper end of chain stay is set in two by bearing respectively before described two, the side of inclusion of described steering mechanism To disk, upper torsional pole, upper cardan, middle torsional pole, lower cardan, driving gear, driven gear, under Torsional pole, lower longitudinal torque arm, lower cross-tie, torsion base, telescopic shaft and overcoat assembly, diplopore plain film Bearing group, setting torsion bar, upper horizontal torque arm, upper longitudinal tie, described steering wheel frame is located on vehicle body frame, Sheathed upper and lower two buttons of described upper torsional pole are held and are connected with steering wheel and upper cardan, and described middle torsional pole is sheathed Upper and lower two bearings are connected with upper cardan and lower cardan respectively, the sheathed bearing of described driving gear, on Side is connected with lower cardan, side and driven gear are joined directly together, each sheathed one of driven gear upper and lower Bearing is directly connected with lower longitudinal torque arm, be arranged with lower cross-tie bearing be connected with lower longitudinal torque arm, two Side is respectively arranged with bearing and is connected with the front end reversing base, and the rear end of torsion base is arranged with bearing and is fixed on car On stature, the upper end frame reversing base is provided with telescopic shaft and overcoat assembly, and telescopic shaft and overcoat assembly both sides are each Base is connected a sheathed bearing, rear end is arranged with a pair of bearings position with torsion, under diplopore plain film bearing group Hold sheathed a pair of bearings to be connected with telescopic shaft and overcoat assembly, upper end also sheathed a pair of bearings with erect torsion bar Lower end is connected, and the lower end erectting torsion bar is arranged with a bearing, the sheathed bearing in upper end and upper horizontal torque arm It is connected, the front end of upper horizontal torque arm is arranged with bearing and is connected with longitudinal tie, thus driving wheel steering.
