The embodiments described below by referring to the drawings are exemplary and are only used to explain the present application, and cannot be understood as a limitation on the present application.
[0027] As Figs. 1-3The utility model provides a cab suspension, which is used for connecting a cab and a frame 100. The cab suspension comprises a suspension bracket 1, a hydraulic lock assembly 4, a hinged soft pad 5 and a shock absorber. The suspension bracket 1 extends in the vertical direction. The lower end of the suspension bracket 1 is fixedly connected to the frame 100. The upper end of the suspension bracket 1 is provided with a hinged hole 11. The axis of the hinged hole 11 is along the width direction of the frame 100. One end of the hydraulic lock assembly 4 is fixedly connected to the cab. The hinged soft pad 5 is installed in the hinged hole 11. The other end of the hydraulic lock assembly 4 is rotatably connected to the upper end of the suspension bracket 1 through the hinged soft pad 5. Specifically, the hinged soft pad 5 is sleeved in the hinged hole 11. The outer sleeve of the hinged soft pad 5 is matched with the hole wall of the hinged hole 11. One end of the hydraulic lock assembly 4 connected to the suspension bracket 1 is provided with an opening. The part of the suspension bracket 1 provided with the hinged hole 11 is located in the opening of the hydraulic lock assembly 4. The two ends of the hinged soft pad 5 are matched with the inner side wall of the opening of the hydraulic lock assembly 4. The fastener passes through the inner sleeve of the hydraulic lock assembly 4 and the hinged soft pad 5 to connect the hydraulic lock assembly 4 to the suspension bracket 1. Thus, the other end of the hydraulic lock assembly 4 is rotatably connected to the upper end of the suspension bracket 1 through the hinged soft pad 5. When the frame 100 and the cab move relatively, the hydraulic lock assembly 4 rotates relative to the suspension bracket 1. The related structure of the hydraulic lock assembly 4 fixedly connected to the cab and the specific structure of the hinged soft pad 5 in the embodiment are all prior art in the field, which will not be described in detail. The upper and lower hangers of the shock absorber are respectively installed on the hydraulic lock assembly 4 and the suspension bracket 1. The shock absorber is used to hinder the rotation of the hydraulic lock assembly 4 relative to the suspension bracket 1. By arranging the shock absorber, when the frame 100 and the cab move relatively, the shock absorber can absorb energy, thereby improving the smoothness and comfort of the cab. The cab suspension of the embodiment integrates the hydraulic lock assembly 4, the hinged soft pad 5 and the shock absorber on the suspension bracket 1, thereby reducing the types of brackets, reducing the assembly workload, improving the work efficiency, reducing the arrangement difficulty and improving the lightweight of the whole vehicle.
[0028] Further, the shock absorber is arranged at an angle with the suspension bracket 1, so that the suspension bracket 1, the hydraulic lock assembly 4 and the shock absorber form a triangular stable structure, thereby improving the structural stability of the cab suspension, ensuring to provide reliable and stable support for the cab and being able to bear greater cab load. The shock absorber is a spring damping shock absorber or an air bag shock absorber 2. In the embodiment, the shock absorber is preferably the air bag shock absorber 2. Compared with the spring damping shock absorber, the air bag shock absorber 2 has better damping effect and higher energy absorption efficiency, thereby further improving the comfort of the cab.
[0029] Further, as shown in the drawings, Figs. 1-2As shown, the cab suspension also includes a height valve assembly 3, which is mounted on the suspension bracket 1. The height valve assembly 3 is connected to the airbag shock absorber 2 and is used to supply or exhaust air to the airbag shock absorber 2. By supplying or exhausting air to the airbag shock absorber 2 through the height valve assembly 3, the working height of the airbag shock absorber 2 remains constant under any load, or the airbag shock absorber 2 can have different heights under the same load, thus adapting to different vibration damping requirements. The suspension bracket 1 is also provided with an air pipe mounting hole 13 for installing the air pipe of the height valve assembly 3, further improving the level of integration. The specific structure of the height valve assembly 3 is prior art in this field and will not be described in detail here.
[0030] Specifically, the suspension bracket 1 is also provided with two height valve mounting holes 12. One end of the height valve assembly 3 is mounted on the suspension bracket 1 through the two height valve mounting holes 12, and the other end of the height valve assembly 3 and the upper hanger of the shock absorber are mounted together at the same mounting point of the hydraulic lock assembly 4, thereby further improving the integration of the cab suspension. The lower end of the suspension bracket 1 is provided with four bracket mounting holes 14, and fasteners pass through the bracket mounting holes 14 to fix the suspension bracket 1 to the frame 100. Along the height direction of the suspension bracket 1, a flange structure is provided on a part of the suspension bracket 1, and the protrusion direction of the flange structure is away from the frame 100. The flange structure is provided with shock absorber mounting holes 15, and the lower hanger of the shock absorber is mounted on the suspension bracket 1 through fasteners. By providing the flange structure, the lower hanger of the shock absorber has more working space when installed with the suspension bracket 1, which facilitates assembly. Two flange structures are set up, and the two flange structures are set in parallel. The lower hanger of the shock absorber is located between the two flange structures, and the lower hanger of the shock absorber is more firmly installed on the suspension bracket 1.
[0031] Optionally, such as Fig. 3 As shown, the suspension bracket 1 has multiple weight-reducing holes, which are spaced apart along the height direction of the suspension bracket 1. The weight-reducing holes facilitate the lightweighting of the suspension bracket 1. All weight-reducing holes are elongated oval holes, extending along the height direction of the suspension bracket 1, thus achieving both weight reduction and structural strength. In this embodiment, three weight-reducing holes are provided: a first weight-reducing hole 16, a second weight-reducing hole 17, and a third weight-reducing hole 18, which are distributed from top to bottom on the suspension bracket 1.
[0032] The utility model provides a kind of vehicle, including frame 100, cab and the cab suspension in the embodiment, suspension support 1 is fixedly connected with frame 100, cab is fixedly connected with hydraulic lock assembly 4.Through setting the cab suspension in the embodiment, the lightweight degree of vehicle is improved, assembly workload in the assembly process of whole vehicle is reduced, assembly efficiency is improved, relevant support variety reduces, arrangement difficulty reduces.
[0033] Obviously, the above embodiments of the utility model are only for clear illustration of the utility model, and are not a limitation on the embodiments of the utility model. For ordinary skilled in the art, other different forms of changes or variations can be made on the basis of the above description. Here, all embodiments cannot be exhausted. Any modification, equivalent replacement and improvement, etc. made within the spirit and principle of the utility model should be included in the protection scope of the utility model claims.
