Abstract
The utility model discloses an overload protection device for vehicles, which belongs to the technical field of vehicle shock-absorption. The device disclosed by the utility model comprises a steel plate spring, the two ends of the steel plate spring are connected to a frame through plate spring connection plates, and the steel plate spring is fixed by a plate spring clamp; the middle part of the steel plate spring is provided with an overload protection pad, the overload protection pad is fixed on a plate spring pressing plate, the plate spring pressing plate is arranged on the steel plate spring, the plate spring pressing plate is provided with two U-shaped bolts, and the U-shaped bolts and a nut assembly fix the plate spring pressing plate and the steel plate spring on a rear axle shaft. According to the overload protection device, an overload protection pad is added on a common plate spring shock-absorption device, so that the protection effect on the shock-absorption device under an overloading condition is achieved, the overload protection on the shock-absorbing plate spring and a whole vehicle is realized flexibly and effectively; and the device is simple in structure, convenient to operate, low in production cost and easy to popularize.
Description
Technical field
The utility model relates to the overload protection device of a kind of vehicle damping system, belongs to the vehicle damping technical field.
Background technology
The existing vehicle especially shock absorption device of electro-tricycle adopts the ordinary steel leaf spring basically, and leaf spring is arranged on the back axle and with vehicle frame and links to each other, and plays the effect of bumper and absorbing shock.But, the phenomenon of overload often appears in the reality, when the actual load-carrying of vehicle above design standard, after the weight that steel leaf spring bears was born weight above theory, steel leaf spring easily produced distortion, and long-time overload easily causes potential safety hazard, reduce the service life of leaf spring, affect the effect of bumper and absorbing shock.
Summary of the invention
In order to address the above problem, the utility model provides a kind of overload of vehicle fender guard, can play a protective role to the leaf spring shock mitigation system in the overload of vehicle situation.
The utility model is achieved by the following technical solution: a kind of overload of vehicle fender guard, and it comprises steel leaf spring, and the two ends of steel leaf spring are connected on the vehicle frame by the leaf spring connecting panel, and described steel leaf spring is fixed by the leaf spring clip; The middle part of described steel leaf spring is equipped with the overload protection pad; the overload protection pad is fixed on the panel spring hold-down plate; panel spring hold-down plate is installed on the described steel leaf spring; two U-bolts are housed on the described panel spring hold-down plate, and U-bolt and nut assembly are fixed on described panel spring hold-down plate and steel leaf spring on the rear axle shaft.
As further improvement, described overload protection pad is rubber cylinder, and the upper end of rubber cylinder is the taper platform, and described overload protection pad vertically is fixed on the described panel spring hold-down plate.
Good effect of the present utility model is: the utility model is equipped with the overload protection pad at the middle part of steel leaf spring; when overload of vehicle; the overload protection pad can withstand on the vehicle frame; reduce the pressure that leaf spring is subject to, prevent that steel leaf spring from producing distortion, realized the overload protection to damping plate spring and car load; effectively provide overload protection to car load flexibly; and simple in structure, easy to operate, be easy to promote.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Accompanying drawing is the utility model structural representation.
Among the figure: 1, steel leaf spring, 2, the leaf spring clip, 3, the overload protection pad, 4, panel spring hold-down plate, 5, U-bolt, 6, the leaf spring connecting panel, 7, plate spring pin roll.
The specific embodiment
A kind of overload of vehicle fender guard comprises steel leaf spring 1 as shown in drawings; The two ends of described steel leaf spring 1 are connected on the vehicle frame by leaf spring connecting panel 6 respectively; Described steel leaf spring 1 is fixing by leaf spring clip 2; Also comprise panel spring hold-down plate 4, overload protection pad 3 and U-bolt 5; Described panel spring hold-down plate 4 is arranged on the middle part of steel leaf spring 1 upper steel plate spring; Described overload protection pad 3 is fixed on the panel spring hold-down plate 4; Described U-bolt 5 passes panel spring hold-down plate 4 and is connected on the rear axle shaft, and fixing by nut and panel spring hold-down plate 4; Described U-bolt 5 is two, and is separately positioned on the both sides of steel leaf spring 1.Described overload protection pad 3 is rubber cylinder, and the upper end of rubber cylinder is the taper platform, and described overload protection pad vertically is fixed on the described panel spring hold-down plate.
Described steel leaf spring 1 is connected by plate spring pin roll 7 with leaf spring connecting panel 6.
Sometimes, the use that can be stacked together of two leaf springs, overload protection pad 3 is installed on the uppermost leaf spring, and of this sort conversion still falls within the protection domain of the present utility model.
When overload of vehicle, the overload protection pad can withstand on the vehicle frame, reduces the pressure that leaf spring is subject to, and prevents that steel leaf spring from producing distortion, realized effectively providing overload protection to car load flexibly to the overload protection of damping plate spring and car load.
