Description
Technical field
This utility model relates to electric motor car and manufactures field, specifically wheel drive five hanging systems in a kind of electric wheel-chair vehicle.
Background technology
Electric wheel-chair vehicle can produce larger vibrations when running into uneven road surface, causes vehicle equilibrium problem, generally need to solve by suspension, existing suspension structure more complicated, manufacturing process is loaded down with trivial details, and manufacturing cost is high, is not suitable for the dillies such as electric wheel-chair vehicle.
Utility model content
In order to solve the above-mentioned technical problem existing in prior art, this utility model provides wheel drive five hanging systems in a kind of electric wheel-chair vehicle, in comprising, take turns, front jockey wheel, rear directive wheel and vehicle frame, the first cradle head, the second cradle head and amortisseur are fixed on described vehicle frame, one end of first connecting rod is connected to described front jockey wheel, the other end is connected to second connecting rod, middle part is fixed on described the first cradle head, the other end of described second connecting rod is connected with the 4th connecting rod, one end of third connecting rod is connected on described the first cradle head, the other end is fixed on Zhong Lun center, the damping spring of described amortisseur is connected to described third connecting rod, the other end of described the 4th connecting rod is connected to described the second cradle head, one end of the 5th connecting rod is connected to described the second cradle head, the other end is connected to described rear directive wheel.
In electric wheel-chair vehicle of the present utility model, wheel drive five hanging system structure are simple, and manufacture process is simple, are applicable to the dillies such as electric wheel-chair vehicle.
Accompanying drawing explanation
Fig. 1 is the structural representation of wheel drive five hanging systems in electric wheel-chair vehicle of the present utility model;
Fig. 2 be in this electric wheel-chair vehicle wheel drive five hanging systems by the schematic diagram of uneven road surface.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As illustrated in fig. 1 and 2, wheel drive five hanging systems in electric wheel-chair vehicle of the present utility model, in comprising, take turns 1, front jockey wheel 2, rear directive wheel 3 and vehicle frame 4, the first cradle head 5, the second cradle head 6 and amortisseur 7 are fixed on vehicle frame 4, one end of first connecting rod 8 is connected to front jockey wheel 2, the other end is connected to second connecting rod 9, middle part is fixed on the first cradle head 5, the other end of second connecting rod 9 is connected with the 4th connecting rod 11, one end of third connecting rod 10 is connected on the first cradle head 5, the other end is fixed on middle 1 the center of taking turns, the damping spring of amortisseur 7 is connected to third connecting rod 10, the other end of the 4th connecting rod 11 is connected to the second cradle head 6, one end of the 5th connecting rod 12 is connected to the second cradle head 6, the other end is connected to rear directive wheel 3.
This utility model be take middle wheel drive electric wheel-chair vehicle and is what platform was realized, during car load power comes from, takes turns 1, before and after middle wheel, respectively has directive wheel as supplemental support and guiding.Core is the damping form of middle wheel (drivewheel), front and back directive wheel, and each wheel is realized the automatic distribution function of geostatic pressure under actual motion state.
Amortisseur practical function is in drivewheel (middle wheel), front and back directive wheel is the pressure of automatic distribution portion to ground in respectively therefrom taking turns by the effect of a stabiliser bar, thereby realize six and take turns uniform stressed, (by distributing the ratio of respectively taking turns load to the adjustment of mechanism) prevents from skidding.Under running status, any one takes turns the various impacts that are subject to can synchronously be assigned on other two-wheeled, make riding personnel feel comfortable, and complete machine manufacturing cost is lower, obtains good effect.
Shown in the above and figure is only preferred implementation of the present utility model.It should be pointed out that for the person of ordinary skill of the art, not departing under the prerequisite of this utility model principle, can also make some modification and improvement, these also should be considered as belonging to protection domain of the present utility model.
