Embodiment 1

[0018] The handle includes a composite spring whose upper end is fixed on the horizontal rail of the bus and an elastic suspension ring connected to the lower end of the spring. The alloy spring is processed by the following components and ratio of raw materials: C: 0.3500%, Si: 0.8000%, Mn: 2.200%, P: 0.0800%, S: 0.003%, Cr: 0.7000%, Sc: 0.0600 %, Al: 0.0005%, N: 0.0100%, and the balance is Fe and unavoidable impurities. The elastic Eucommia gum is made according to the following components and proportions: 95 parts of Eucommia gum, 85 parts of rubber additive, 7 parts of sulfur, 5 parts of sulfur-containing accelerator, 5 parts of ZnO, 5 parts of CaO, 11 parts of resin modifier, carbon 80 parts of black, 4 parts of anti-aging agent.

Embodiment 2

[0020] The handle includes a composite spring whose upper end is fixed on the bus horizontal pole through a wire rope and an elastic suspension ring connected to the lower end of the spring. The alloy spring is processed by the following components and ratio of raw materials: C: 0.7000%, Si: 4.5200%, Mn: 0.1600, P: 0.003, S: 0.0800%, Cr: 3.80%, Sc: 0.0015, Al : 0.0500%, N: 0.0020%, and the balance is Fe and unavoidable impurities. The elastic eucommia gum is made according to the following components and proportions: 15 parts of eucommia gum, 5 parts of rubber additives, 3 parts of sulfur, 1 part of sulfur-containing accelerator, 1 part of ZnO, 1 part of CaO, 1 part of resin modifier, carbon 30 parts of black, 2 parts of anti-aging agent.

Embodiment 3

[0022] The handle includes a composite spring whose upper end is fixed on the horizontal pole of the bus by screws and an elastic suspension ring connected to the lower end of the spring. The alloy spring is processed by the following components and ratio of raw materials: C: 0.5500%, Si: 2.6500%, Mn: 1.080%, P: 0.0190%, S: 0.0420%, Cr: 2.256%, Sc: 0.0308 %, Al: 0.0250%, N: 0.0060%, and the balance is Fe and unavoidable impurities. The elastic Eucommia gum is made according to the following components and proportions: 55 parts of Eucommia gum, 45 parts of rubber additive, 5 parts of sulfur, 3 parts of sulfur-containing accelerator, 3 parts of ZnO, 3 parts of CaO, 6 parts of resin modifier, carbon 55 parts of black, 3 parts of anti-aging agent.

[0023] The bus spring handle made of the above embodiments has excellent damping effect, can bear load and large deformation, has stable vibration mechanical performance, is safe to use, and has a long service life.

Abstract

The invention relates to a spring handgrip for a bus. The spring handgrip for the bus comprises a composite spring of which the upper end is fixed on a horizontal handrail of the bus, and an elastic hanging ring connected at the lower end of the spring, wherein the composite spring comprises an alloy spring; the alloy spring is coated with an elastic gutta percha composite layer through casting moulding to form a composite spring body; the elastic hanging ring is made of at least one of plastic or rubber. The spring handgrip for the bus has excellent damping effect, can withstand load and a relatively large amount of deformation, and is stable in vibratory mechanical property, safe to use and long in service life.

Description

technical field [0001] The invention relates to a bus component, in particular to a bus spring handle. Background technique [0002] The bus handle is an essential component of the bus. In the prior art, the bus handle is generally designed as the following structure: the upper end is fixed on the handrail, the middle is a connected soft belt, and the lower end of the soft belt is connected to a hard ring. The handle of this structure has the following during use Defect: During the process of parking, driving, turning, etc., the hand holding the suspension ring takes the fixed point as the center of the circle, and the hand that pulls the soft belt swings in a conical surface. The range of movement space is large, and the balance of the body suffers. damage and poor stability, it is easy to cause mutual collision between passengers and friction between passengers and the car body, resulting in physical injury to passengers; moreover, the impulsive force generated by the sud...
