Description

Technical Field

[0001] The utility model relates to the technical field of skid-steer loaders, and particularly relates to an extended-range skid-steer loader. Background Art

[0002] At present, traditional skid-steer loaders need to use power batteries with low energy density as power units to supply power to the whole vehicle. When operating in the wild for a long time or in some areas with insufficient power facilities, once the battery runs out of power, the whole vehicle will not be able to work and move. Content of the Utility Model

[0003] In order to solve the problem in the prior art that the power battery supplies power to the whole vehicle and the loader cannot move due to the inability to supply power in time, the utility model provides an extended-range skid-steer loader that enhances the operation endurance of the skid-steer loader under non-charging conditions.

[0004] The technical solution adopted by the utility model to solve its technical problems is as follows:

[0005] An extended-range skid-steer loader, comprising:

[0006] A generator set, the generator set includes an engine and a generator connected to the engine;

[0007] A power battery, the power battery is connected to the generator, and the generator charges the power battery

[0008] A traveling system, the power battery supplies power to the traveling system;

[0009] A working system, the power battery supplies power to the working system.

[0010] Further, the traveling system includes a traveling motor, and the traveling motor is connected to the power battery. The traveling system is driven by a motor, and has good power.

[0011] Further, the traveling system further includes a traveling speed reducer, and the traveling speed reducer is connected to the traveling motor.

[0012] Further, the working system includes a working motor, and the working motor is connected to the power battery.

[0013] Further, the working system further includes a working hydraulic pump connected to the output end of the working motor, and the working hydraulic pump is connected to a hydraulic system. Adopting the structural form of combining a motor and a pump can provide efficient power output.

[0014] Further, the hydraulic system includes a control valve connected to the working hydraulic pump, and the control valve is connected to a working device. By connecting the control valve to the working device, the flow rate of the working device can be adjusted.

[0015] Furthermore, the working device includes a lifting oil cylinder, a bucket cylinder, and a hydraulic accessory power take-off port.

[0016] Furthermore, the engine is a diesel engine.

[0017] Beneficial effects:

[0018] (1) The present utility model solves the endurance problem of the whole vehicle of the electric skid steer loader when the charging conditions are not met, and at the same time alleviates the endurance anxiety of customers when using the electric skid steer loader product. Therefore, it provides a power supply solution for the electric skid steer loader under the condition that the charging facilities are not met, and also enables the electric skid steer loader to have a good market application in some areas where diesel is sufficient but power facilities are insufficient.

[0019] (2) The present utility model mounts a diesel engine + generator on the electric skid steer loader to generate electricity for the power battery. Since the diesel engine does not provide the load required for the whole vehicle to work, but only provides the power unit for the whole vehicle to charge, a small-horsepower engine can be selected and power generation operations can be carried out in the most economical fuel consumption range. Therefore, the endurance ability of the electric skid steer loader will be greatly enhanced, overcoming the working time in the field and the working environment where the charging facilities are not perfect.

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and in no way limits the present utility model and its application or use. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0024] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present application. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0025] Unless otherwise specifically stated, the relative arrangements, numerical expressions, and numerical values of the components and steps described in these embodiments do not limit the scope of the present utility model. At the same time, it should be understood that, for the sake of convenience of description, the dimensions of the various parts shown in the drawings are not drawn in actual proportional relationships. Technologies, methods, and devices known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and devices should be regarded as part of the description. In all the examples shown and discussed herein, any specific value should be construed as merely exemplary and not as a limitation. Therefore, other examples of the exemplary embodiments may have different values. It should be noted that: like reference numerals and letters denote like items in the following drawings, and thus, once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0026] In the description of the present utility model, it should be understood that the orientation or positional relationships indicated by orientation words such as "front, back, up, down, left, right", "horizontal, vertical, perpendicular, horizontal", and "top, bottom" are usually based on the orientation or positional relationships shown in the drawings, and are only for the convenience of describing the present utility model and simplifying the description. Without contrary description, these orientation words do not indicate and imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and thus cannot be construed as limiting the scope of protection of the present utility model; the orientation words "inside, outside" refer to the inside and outside relative to the contour of each component itself.

[0027] For ease of description, spatial relative terms such as "above", "over", "on the upper surface", "upper" etc. can be used here to describe the spatial positional relationship between a device or feature shown in the figure and other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation in addition to the orientation depicted in the figure for the device. For example, if the device in the drawing is inverted, a device described as "above or over other devices or structures" will then be positioned "below or under other devices or structures". Thus, the exemplary term "above" can include both the orientations of "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and corresponding interpretations are made for the spatial relative descriptions used here.

[0028] In addition, it should be noted that the use of terms such as "first", "second" etc. to define components is only for the convenience of differentiating the corresponding components. Without additional statements, the above terms have no special meanings, and thus should not be construed as limiting the protection scope of the present utility model.
