Description

Technical Field

[0001] The invention relates to the technical field of tourist buses, and in particular to a tourist bus with a high-performance steering system. Background Art

[0002] As environmental pollution becomes increasingly serious, people are calling for protecting the natural ecological environment and saving energy, and the requirements for tourist buses to have energy-saving and environmentally friendly characteristics are also increasing accordingly. Most cars in the existing technology use gasoline as fuel, but cars using gasoline as fuel consume a lot of fuel and pollute the environment. In order to meet the above requirements, electric tourist buses are gradually entering the tourism industry. Electric tourist buses can meet the requirements of energy conservation and environmental protection. Electric tourist buses have the advantages of novel and unique appearance, high configuration, high performance (power performance, braking performance, climbing performance), low energy consumption, easy maintenance, and good safety performance. They are a means of transportation for scenic spots, large amusement parks, parks, closed communities, resorts, pedestrian streets, university campuses, airports, ports, docks and other tourist sightseeing places and workplaces.

[0003] The steering system of electric sightseeing buses on the market currently usually adopts a method of connecting the steering wheel to the steering shaft, connecting the steering shaft to the lower shaft rod through a universal joint, and finally directly connecting the lower shaft rod to the steering gear through a universal joint. This connection method results in a relatively fixed installation position of the steering system, which has certain limitations. At the same time, when the front wheels and the ground generate reverse resistance during the driving of the sightseeing bus, it is easy to directly transmit the resistance to the driver through the shaft in the steering system, thereby affecting the steering performance. Therefore, a sightseeing bus with a high-performance steering system is provided to solve the above problems. Summary of the invention

[0027] Please refer to Figure 1-Figure 6 The present invention discloses a tourist bus with a high-performance steering system, comprising: a tourist bus frame 1, a steering mechanism is arranged at the head of the tourist bus frame 1, the steering mechanism comprises a steering body 2, an oblique steering straight tie rod 5, a right-angle reversing gear 6, a lower shaft rod 7, a steering booster 8, and a steering shaft 9, both ends of the oblique steering straight tie rod 5 are connected with universal joints, one end of the oblique steering straight tie rod 5 is connected to the input end of the steering body 2 through a universal joint, and the other end of the oblique steering straight tie rod 5 is connected to the right-angle reversing gear 6 through a universal joint, both ends of the lower shaft rod 7 are connected with universal joints, and the bottom end of the lower shaft rod 7 is connected with a universal joint. The right-angle reversing gear 6 is connected through a universal joint, and the upper end of the lower shaft rod 7 is connected to the output end of the steering booster 8 through a universal joint. The input end of the steering booster 8 is connected to the steering shaft 9. The right-angle reversing gear 6 is used as an intermediate connecting piece. The length and direction of the oblique steering straight pull rod 5 can be adjusted at will according to the specifications, thereby effectively increasing the steering wheel power arm. When the front wheel 17 is subject to external reverse steering resistance during driving, the person can stably and efficiently control the steering wheel 10 to steer, and at the same time, the bumpy feeling transmitted by the front wheel 17 can be effectively filtered through the right-angle reversing gear 6.

[0028] Combination Figure 2 and Figure 3As shown, the steering body 2 is fixedly installed at the bottom of the front end of the sightseeing bus frame 1, and the output end on one side of the steering body 2 is connected to the first steering rod 3, and the output end on the other side of the steering body 2 is connected to the second steering rod 4. The first steering rod 3 and the second steering rod 4 can be used to synchronously control the first front wheel seat 11 and the second front wheel seat 12 to steer. The first steering rod 3 is connected to the first front wheel seat 11 at one end away from the steering body 2, and the second steering rod 4 is connected to the second front wheel seat 12 at one end away from the steering body 2. The bottoms of the first front wheel seat 11 and the second front wheel seat 12 are both connected to a lower swing arm 13 through an axis, and one end of the lower swing arm 13 is connected to the bottom of the sightseeing bus frame 1 through an axis. A diagonal rod 14 is arranged on one side of the upper end of the lower swing arm 13, and one end of the diagonal rod 14 is connected to the bottom of the sightseeing bus frame 1. The steering booster 8 is installed at the head of the sightseeing bus frame 1, and a steering wheel 10 is installed at the top of the steering shaft 9. The upper ends of the first front wheel seat 11 and the second front wheel seat 12 are both connected to a shock absorber 15, and the top of the shock absorber 15 is connected to the sightseeing bus frame 1.
